Book Evidence for Anomalous Nuclei Among Relativistic Projectile Fragments from Heavy Ion Collisions at Bevalac Energies

Download or read book Evidence for Anomalous Nuclei Among Relativistic Projectile Fragments from Heavy Ion Collisions at Bevalac Energies written by and published by . This book was released on 1980 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Two independent emulsion experiments using Bevalac beams of 16O and 56Fe at H" GeV/nucleon find with> 99.7% confidence that the reaction mean-free paths of projectile fragments, 3 H" Z H" 26, are shorter for a few centimeters after their emission than at larger distances, or than predicted from experiments on beam nuclei. This effect, which is enhanced in later generations of fragments, can be interpreted by the relatively rare occurrence of fragments that interact with an unexpectedly large cross section.

Book Nuclear Breakup and Particle Densities in 200 A GeV 16O Interactions with Emulsion Nuclei

Download or read book Nuclear Breakup and Particle Densities in 200 A GeV 16O Interactions with Emulsion Nuclei written by and published by . This book was released on 1987 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Experiment EMU-01 makes use of emulsion chambers and conventional stacks to study the interactions in matter of 200 A GeV 16O nuclei accelerated at the CERN SPS. Projectile fragmentation is compatible with such interactions of 16O nuclei at 2 A GeV, indications of limiting fragmentation. Particle production is examined via high precision pseudo-rapidity distributions. Energy densities up to about 3 GeVfm3 are observed in central 16O + Ag(Br) interactions. Pseudo-rapidity density distributions and fluctuations are well reproduced by the MC model Pritiof, although the existence of new and unknown sources of density fluctuations are not excluded by the data. 7 refs., 7 figs.

Book Energy Spectra of Fragments from Silver and Uranium Bombarded With5 0 GeV Protons

Download or read book Energy Spectra of Fragments from Silver and Uranium Bombarded With5 0 GeV Protons written by and published by . This book was released on 1972 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: In this third paper in a series in which the characteristics of nuclear fragments produced in the interaction of 5 GeV protons with Ag and U targets were studied by means of dE/dx-E measurements with semiconductor detector telescopes new information was obtained on the energy spectra of light fragments. One set of measurements on fragments from a Ag target involved the use of a two-element telescope incorporating a [Delta]E detector as thin as 16 [mu]m. A new algorithm for processing the [Delta]E and E data to extract particle identification was developed and the resulting particle spectra showed superior resolution for the elements from Li(Z = 3) to S (Z = 16). Segments of the energy spectra of each of these elements were measured at 20{sup o} and, for many of them, also at 45{sup o}, 90{sup o}, 135{sup o} and 160{sup o} to the beam direction. By use of 3-element telescopes and absorbers the high energy part of the energy spectrum for isotopes of He, Li, Be, B, and C ejected from Ag and U targets was measured at 20{sup o}. The measurements extended beyond 300 MeV for 6Li and 7Li and to 400 MeV for 7Be. A distinct high-energy component was found in these cases. The suitability of nuclear evaporation as a description of the emission of the low-energy fragments was tested with two simple theoretical models, one specifying isotropic fragment emission from a moving nucleus at a fixed nuclear temperature and one specifying isotropic fragment emission from a set of moving nuclei with a Maxwellian distribution of excitation energies and forward momenta. The second could describe rather well all the 90{sup o} data, provided a Coulomb barrier 0.4 that of the classical tangent spheres barrier was used. However, the measured intensity in the forward direction was much higher than predicted. Neither evaporation calculation was able to describe the highest energy part of the spectra, and the conclusion was drawn that these particles must be produced in the initial high-energy cascade.
