Book excerpt: The complexities of the s-shell .lambda.-hypernuclei (A less than or equal to 5) are explored. Difficulties associated with attempts to describe the hyperon-nucleon (YN) interaction in all such .lambda.-hypernuclei by simple, effective .lambda.p and .lambda.n potentials are examined. The explicit A dependence of the effective YN interaction due to .lambda. N-.sigma. N coupling and isospin differences among the nuclear core states is investigated. The necessity of using exact four-body theory to calculate small charge-symmetry-breaking effects (in the A = 4 system) using .lambda. N potentials fitted to free .lambda. N scattering data is emphasized. Possible use of s-shell hypernuclear binding energies to help distinguish among candidate YN potential parameterizations is discussed.

Available in PDF, EPUB and Kindle. Book excerpt: Empirical data on the spectra of light hypernuclei, especially the data from recent[gamma]-ray experiments, is used to constrain the parameters which govern the P[sub N]s[sub[Lambda]] and p[sub N]p[sub[Lambda]]j two-body matrix elements that enter into shell-model calculations.

Book excerpt: The inclusion of Lambda N-.sigma. N coupling in the A = 4 Lambda-hypernuclei is shown to be required in order to obtain proper ordering of the 0 ground state and 1 spin-flip excited state, when exact four-body equations are solved. It is argued that suppression of the off-diagonal Lambda N-.sigma. N coupling in the A = 5 system, similar to that in the A = 4 isodoublet, should account for the anomalously small binding of 5He. An alternative quark model explanation is also considered.

Book excerpt: Few Particle Problems in the Nuclear Interaction emerged from the International Conference on Few Particle Problems in the Nuclear Interaction held in Los Angeles, from August 28-September 1, 1972. The aim of the conference was to discuss recent developments in low and medium energy few-particle problems. This included the fields of the nuclear three-body problem; nuclear forces (in particular, three-body forces); symmetries; and the interaction of mesons, leptons, and photons with few-nucleon systems. Special sessions were also devoted to the application of the results and techniques of the few-particle research to the problems of other fields, in particular nuclear structure and astrophysics. The conference was organized into nine plenary sessions and 13 parallel sessions. This volume contains 184 papers presented during the nine sessions on the following topics: the nucleon-nucleon interaction; three-body forces; hypernuclear systems; symmetries; three-body problems; multiparticle reactions; proposed studies of few-nucleon systems with meson factories; few-nucleon systems and leptons, mesons, and photons; and applications.

Download or read book Handbook of Nuclear Physics written by Isao Tanihata and published by Springer Nature. This book was released on 2023-09-04 with total page 4180 pages. Available in PDF, EPUB and Kindle. Book excerpt: This handbook is a comprehensive, systematic source of modern nuclear physics. It aims to summarize experimental and theoretical discoveries and an understanding of unstable nuclei and their exotic structures, which were opened up by the development of radioactive ion (RI) beam in the late 1980s. The handbook comprises three major parts. In the first part, the experiments and measured facts are well organized and reviewed. The second part summarizes recognized theories to explain the experimental facts introduced in the first part. Reflecting recent synergistic progress involving both experiment and theory, the chapters both parts are mutually related. The last part focuses on cosmo-nuclear physics—one of the mainstream subjects in modern nuclear physics. Those comprehensive topics are presented concisely. Supported by introductory reviews, all chapters are designed to present their topics in a manner accessible to readers at the graduate level. The book therefore serves as a valuable source for beginners as well, helping them to learn modern nuclear physics.

Book excerpt: The present status of structure calculations for p-shell .lambda. hypernuclei, including the phenomenological determination of .lambda. N effective interaction matrix elements, is briefly reviewed. For .sigma. hypernuclei the Nijmegen potential model D is used for guidance in constructing .sigma. N effective interactions. The structure of /sub .sigma./12Be and /sub .sigma./12C, including isospin mixing in the later case, is discussed, and a comparison is made with experimental data. 19 refs., 5 figs., 4 tabs.

Available in PDF, EPUB and Kindle. Book excerpt: Variational Monte Carlo calculations have been made for the s-shell hypernuclei and also of /sub .lambda./9Be with a 2.cap alpha. + .lambda. model. The well depth is calculated variationally with the Fermi hypernetted chain method. A satisfactory description of all the relevant experimental .lambda. separation energies and also of the .lambda.p scattering can be obtained with reasonable TPE .lambda. N and .lambda. NN forces and strongly repulsive dispersive .lambda. NN forces which are preferred to be spin dependent. We discuss variational calculations for /sub .lambda lambda./6He and /sub .lambda lambda./1°Be with .cap alpha. + 2.lambda. and 2.cap alpha. + 2.lambda. models, and the results obtained for the .lambda lambda. interaction and for /sub .lambda lambda./6He from analysis of /sub .lambda lambda./1°Be. Coulomb effects and charge symmetry breaking in the A=4 hypernuclei are discussed. 28 refs.
