Available in PDF, EPUB and Kindle. Book excerpt: A brief description of the procedure and highlights of the calculations performed on a broad range of p-shell nuclei including .lambda.9Be, .lambda.12C, .lambda.13C, .lambda.14N and .lambda.16O for which data exist and .lambda.1°B, .lambda.14C, .lambda.15N for which data do not exist are given. The mechanism for the (K−, .pi.−) reaction which generates the rich excitation spectra seen experimentally is briefly considered. The use of a relativistic DWBA formalism includes naturally the distortion in K−, .pi.− wave functions and permits quantitatively reliable estiamtes of reaction cross-sections to be made. An essentially complete treatment of second-half p-shell nuclei with fixed .lambda. N and NN potentials is possible because of the small size variations of these nuclei. In principle at least a three body .lambda. NN force should be present, inducing an apparent nucleon-number dependence in an effective two body interaction. The emphasis is on extraction, from the hypernuclear spectrum and excitation probabilities, of details of the .lambda. N interaction not otherwise obtainable experimentally. (WHK).

Book excerpt: The (.pi., K) reaction was used to study lambda hypernuclear states in /sub .lambda./9Be, /sub .lambda./12C, /sub .lambda./13C, /sub .lambda./16O, /sub .lambda./28Si, /sub .lambda./4°Ca, /sub .lambda./51V and /sub .lambda./89Y. The results show that the (.pi.+, K+) reaction is ideally suited for populating lambda single particle states in heavy nuclei. 14 refs., 3 figs.
Download or read book Observation Of Lambda hypernuclei in the Reaction 12C Pi K written by and published by . This book was released on 1985 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The observation of .lambda.-hypernuclear levels in /sub .lambda./12C by associated production through the (.pi., K) reaction is reported. Spectrometers used in the measurements are discussed. The /sub .lambda./12C excitation energy spectra were recorded at laboratory scattering angles of 5.6°, 10.3°, and 15.2°. The spectra show two major peaks - one attributed to the ground state, and one about 11 MeV higher in excitation. The peak near 11 MeV excitation energy is believed to be almost entirely composed of a multiplet of three J/sup .pi./ = 2 states. Relativistic DWBA calculations imply support for the expectation that higher spin states are preferentially populated in the (.pi.+, K+) reaction, compared to the (K−, .pi.−) reaction in which lower spin states are excited. 29 refs., 40 figs.

This book was released on 2000-09-27 with total page 462 pages. Available in PDF, EPUB and Kindle. Book excerpt: The unique role of strangeness in nuclear physics has recently attracted much attention, from both the theoretical and experimental viewpoints. This is due not only to the broad spectrum of possible hadron many-body systems with strangeness, but also to the fact that strangeness gives us an opportunity to study fundamental baryon-baryon interactions in a new perspective. Our knowledge of this subject has widened as the scope of hypernuclear experiments has expanded from strangeness exchange and the associated production reactions to hypernuclear weak decays, β decays, cascade hypernuclei, double-Λ events, electroproduction of strangeness, etc. This trend will be accelerated by the full operation of new laboratories such as TJLab, COSY, DAΦNE, JHF, MAMI, and others. Various aspects of those important and exciting topics are discussed in this book in order to get a perspective of this fast developing area of nuclear physics.

Book excerpt: The study of hypernuclei affords unique insights into the nature of hadronic forces beyond those obtainable from ordinary nuclear physics research. A hypernucleus consists of one or more hyperons bound to a nuclear core. In the SU(3) classification, [Lambda], [Sigma], and [Xi] hyperons occupy the same octet representation of spin-parity /1/2/ baryons as the neutron and proton, the familiar constituents of ordinary nuclei. The [Lambda] and [Sigma] possess strangeness S = -1 and isotopic spin I = 0, 1, respectively, while the /Xi/ has S = /minus/2, I = /1/2/. In the underlying quark picture, the [Lambda] and /Sigma/ have the flavor structure s(ud)/sub I=0, 1/, compared to the combination uud for the proton. The strange quark, s, carries the strangeness quantum number S = /minus/1, which makes it distinguishable from the S = 0 u and d quarks. The lowest-lying hyperon is the /Lambda/, with a mass of 1,115.6 MeV/c2, some 177 MeV/c2 heavier than the proton. The study of the behavior of a hyperon embedded in the nuclear medium, through the theoretical analysis of level spectra, sheds light on the nature of the hyperon-nucleon (YN) effective interaction, i.e. on the role of the strange quark in strong interactions. This paper investigates the ([pi], K/sup +/) reactions that produce hypernuclei. 32 refs., 5 figs., 2 tabs.

Available in PDF, EPUB and Kindle. Book excerpt: This book aims to provide a detailed introduction to the state-of-the-art covariant density functional theory, which follows the Lorentz invariance from the very beginning and is able to describe nuclear many-body quantum systems microscopically and self-consistently. Covariant density functional theory was introduced in nuclear physics in the 1970s and has since been developed and used to describe the diversity of nuclear properties and phenomena with great success.In order to provide an advanced and updated textbook of covariant density functional theory for graduate students and nuclear physics researchers, this book summarizes the enormous amount of material that has accumulated in the field of covariant density functional theory over the last few decades as well as the latest developments in this area. Moreover, the book contains enough details for readers to follow the formalism and theoretical results, and provides exhaustive references to explore the research literature.

Available in PDF, EPUB and Kindle. Book excerpt: Hypernuclear production through the (e, e'K+) reaction makes it possible to realize sub-MeV high-resolution spectroscopy of  hypernuclei thanks to the availability of high quality primary beams. It is in contrast to the (K?, L?) and (L+, K+) reactions which use secondary beams of pions and kaons. Even though hypernuclear cross sections are much smaller than those from meson beams, the (e, e?K+) reaction has advantageous features for  hypernuclear production. A goal of the present study is to further explore and establish (e, e?K+) spectroscopy as a tool to investigate  hypernuclei, succeeding the pioneering experiment JLab E89-009, which was successfully carried out previously. A 1.8 GeV electron beam hit targets at the entrance of the splitter magnet in JLab?s Hall C.A positive kaon and a scattered electron were deflected by the splitter magnet to opposite directions and guided to the high resolution kaon spectrometer (HKS) and the scattered electron spectrometer (Enge), respecti.
