Available in PDF, EPUB and Kindle. Book excerpt: Two years ago, at the 12th Winter Workshop on Nuclear Dynamics held here in Snowbird, the authors presented WA80 limits on direct photon production in 200-GeV 32S + Au collisions. It was found that the results were consistent (within 1[sigma]) with the absence of an excess of photons over those that can be accounted for by the two-photon decay branches of [pi]° and [eta] mesons and by the small photon contributions from other radiative decays. They are in the process of finalizing the direct-photon production results from collisions of lead nuclei at 158 GeV/nucleon. The author briefly discusses the status of the analysis and gives some preliminary results at the end of this talk. However, most of this presentation is concerned with a very different aspect of the photon measurements: distributions of neutral pions. In contrast to direct photons which probe initial collision conditions, hadrons, such as neutral pions, interact strongly and decouple late in the reaction evolution and, thus, provide information concerning the system at freeze out. Transverse momentum spectra at low and intermediate p{sub T} relate to thermodynamic and hydrodynamic descriptions of the hot, dense systems. In addition, the high-p{sub T} region reflects the hard-scattering regime and may help one understand initial-state particle production by forming a bridge to proton-proton and proton-nucleus results. It follows that it is essential that the [pi]° measurements cover a large p{sub T} range.

This book was released on 2019-01-13 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: Space radiation transport codes require accurate models for hadron production in intermediate energy nucleus-nucleus collisions. Codes require cross sections to be written in terms of lab frame variables and it is important to be able to verify models against experimental data in the lab frame. Several models are compared to lab frame data. It is found that models based on algebraic parameterizations are unable to describe intermediate energy differential cross section data. However, simple thermal model parameterizations, when appropriately transformed from the center of momentum to the lab frame, are able to account for the data. Norbury, John W. and Blattnig, Steve R.

This book was released on 1995-02-17 with total page 882 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the main goals of intermediate energy nuclear physics, which serves an important role as a bridge between nuclear and particle physics, is to construct the theory of strong interaction phenomena in terms of conventional degrees of freedom (nucleons, deltas and mesons) as well as of quark degrees of freedom.The main topics to be discussed at this conference are the interaction of pions and other mesons with nuclei at intermediate energies and the role of mesonic degrees of freedom in nuclear reactions, including photon, hadron and heavy ion induced reactions. Both theoretical and experimental results will be included.Over the past two decades, the Meson Factories, including LAMPF, TRIUMF, and PSI, have provided us with systematic experimental information on hadron-hadron and hadron-nucleus dynamics. Major accelerators of JINR are also suitable for studying problems in Intermediate Energy Nuclear Physics. At the present time, first experiments have been performed with the proton beams at the Moscow Meson Factory of INR. One of the purposes of this conference is to introduce the intermediate-energy physics community to the possibility of utilizing the facilities of JINR and INR during the next decade.

Available in PDF, EPUB and Kindle. Book excerpt: A general review of experimental data on pion production in A-A collisions for incident energies below a few GeV/nucleon is presented. Early data on inclusive pion spectra, which served as the genesis for present pion measurements, are discussed. The majority of the paper is devoted to present pion experiments, with an emphasis being placed on what such experiments tell about the general features of high-energy A-A collisions. Particular attention is given to multipion production as studied in recent streamer chamber experiments. The review ends with projections on future experiments with the heavier beams that will be available in 1982 at Berkeley, and the higher-energy beams that will hopefully be available in the not too distant future. 39 figures.

Download or read book Intermediate Energy Nuclear Physics written by A. S. Iljinov and published by CRC Press. This book was released on 1994-01-27 with total page 388 pages. Available in PDF, EPUB and Kindle. Book excerpt: Intermediate-Energy Nuclear Physics is devoted to discussing the interaction between hadrons with nuclei, which leads to the emission of particles during an intranuclear cascade and subsequent decay of a highly excited residual nucleus. Experimental data and the methods and results of the calculation of probabilities of various processes initiated by intermediate-energy hadrons in nuclei are set forth and discussed. The potential for obtaining information on the structure and properties of nuclei by comparing experimental data with theoretical results is analyzed. New issues, such as analytic methods for the solution of kinetic equations describing the cascade, nuclear absorption of hadrons from bound states of hadronic atoms, interaction of antinucleons with nuclei, multifragmentation of highly excited residual nuclei, and polarization phenomena, are discussed in detail. The book also demonstrates hadron-nucleus interactions that bridge the gap between low-energy and heavy ions physics. It is an interesting reference for nuclear physicists and other researchers interested in the analysis of problems associated with the evolution of the early (hot) universe, neutron stars and supernovas, after-burning of radioactive waste in nuclear energy installations, and electronuclear energy breeding.

Book excerpt: There has been considerable recent interest in the nuclear equation of state and how it may be determined in relativistic nucleus-nucleus collisions. In these collisions extremely high temperatures are reached and compression to densities several times that of normal nuclear matter are predicted. This affords us the unique opportunity to study, in a somewhat controlled manner, the behavior of nuclear matter under these extreme conditions. If the observables that are measured in experiments can be related in a quantitative way to state variables of the system then the equation of state can be extracted. This relation plays a very important role in understanding the formation and collapse of supernovae and the stability and structure of neutron stars. Furthermore, it can be used to test and constrain field theoretical approaches to nuclear matter and to help to better understand the dynamics of high energy nucleus-nucleus collisions. In this presentation the relationship between the nuclear equation of state and relativistic nucleus-nucleus collisions will be discussed with an emphasis on how to extract the former. That a high density state of the collision should exist will be shown. One observable, namely the pion multiplicity, will be shown to survive the succeeding stages of the collision process to provide information on the equation of state at high densities. The resulting equation of state will be presented and discussed in the light of recent theoretical development. 34 refs., 12 figs.

This book was released on 1997-10-13 with total page 466 pages. Available in PDF, EPUB and Kindle. Book excerpt: This proceedings volume gives a consistent overview of various theoretical and experimental programs which study the dynamics of nucleus-nucleus collisions from low to ultra-relativistic energies. The contributions concentrate on the following topics: cold fragmentation of nuclear matter, pre-equilibrium and thermalization, thermal and chemical equilibration, fragmentation and correlations in intermediate energy collisions, dynamical properties of hot and dense nuclear matter in medium effects, resonance and strange nuclear matter, and signals of the deconfined state.High quality data obtained using experimental devices close to 4π geometries and recent theoretical developments are presented. They illustrate the significant progress made during the last few years in understanding the properties of nuclear matter in extreme conditions of pressure and temperature.This book serves as a graduate textbook and as a reference work on recent developments in this area.
