[en] This document reports the progress of the research of pion reactions. These include (1) a study to measure observables in the pion-nucleon system in the momentum interval 400 to 700 MeV/c, (2) differential cross section measurements at low energy for pion-nucleon charge exchange, and (3) elastic and inelastic scattering of π^+- on ³H and ³He. Individual experiments will be indexed separately

[en] The objective of this paper was a review of the text 'Theoretical Nuclear Physics: Nuclear Reactions' by Herman Feshbach. It is a follow-on publication to his earlier work 'Theoretical Nuclear Physics'. In the present text, the primary emphasis is on non-relativistic collision and scattering theory, but a substantial segment of the book is dedicated the high-energy, relativistic, and ultrarelativistic interactions. The text closes with a chapter on the interactions of mesons with nuclei

[en] Experimental and theoretical aspects of double-analog, nonanalog, and continuum pion double charge exchange in the 50- to 310-MeV energy range are covered. Separate abstracts were prepared for 22 papers in these proceedings

[en] The experimental situation on pion absorption and production, as established by recent (π,πN), (π,NN), (π, charged X), (π,γX), (π,N) and (N,π) reaction experiments, is reviewed

[en] A generalization of the relativistic eikonal amplitude originally developed to describe elastic scattering between structured particles is introduced. The coherent and incoherent proton-nucleus scattering processes are analysed and closed forms expressions for elastic and inelastic amplitudes are derived. In particular, for incoherent case, an energy conserving version of Glauber's theory is obtained. (author)

[en] National Nuclear Data Center (NNDC) maintains a number of data bases containing bibliographic information and evaluated as well as experimental nuclear properties. An evaluated computer file maintained by the NNDC, called the Evaluated Nuclear Structure Data File (ENSDF), contains nuclear structure information for all known nuclides. The ENSDF is the source for the journal ''Nuclear Data Sheets'' which is produced and edited by NNDC. The Evaluated Nuclear Data File (ENDF), on the other hand is designed for storage and retrieval of such evaluated nuclear data as are used in neutronic, photonic, and decay heat calculations in a large variety of applications. Some of the publications from these data bases are the Nuclear Wallet Cards, Radioactivity Handbook, and books on neutron cross sections and resonance parameters. In addition, the NNDC maintains three bibliographic files: NSR - for nuclear structure and decay data related references, CINDA - a bibliographic file for neutron induced reactions, and CPBIB - for charged particle reactions. Selected retrievals from evaluated data and bibliographic files are possible on-line or on request from NNDC. 6 refs., 1 fig

[en] Progress in theoretical research is reported under the following readings: (1) few nuclear reactions, Eikonal approximations, and optical models; (2) pion reactions; (3) nuclear structure by reaction studies; (4) nuclear dynamics

[en] Version VI of the Evaluated Nuclear Data File (ENDF/B-VI) was released in 1990. For ENDF/B-VI major emphasis was placed on standards, isotopic evaluations, energy balance, improved resonance region representations, and improvement of neutronics files for important actinides. Data testing proceeds at a pace much slower than previous versions but more results are now being accumulated. Two versions have been released to data and a third is planned after the next meeting of the Cross Section Evaluation Working Group (CSEWG), currently planned for October 1994

[en] This report summarizes the work on experimental research in intermediate energy nuclear physics carried out at New Mexico State University in 1991-94 under a grant from the U.S. Department of Energy. Most of these studies involved investigations of various pion-nucleus interactions and nucleon-nucleus charge-exchange reactions. The work was carried out with the LAMPF accelerator at the Los Alamos National Laboratory and the cyclotrons at the Paul Scherrer Institute (PSI) near Zurich, Switzerland, at Indiana University (IUCF), and at TRIUMF in Vancouver, Canada, as collaborative efforts among several laboratories and universities. We have also worked on plans and preparations for new experiments involving studies of the quark structure of nucleons and nuclei, which would be carried out at Fermilab (FNAL), near Chicago, and at the HERA facility at the DESY laboratory in Hamburg, Germany. The NMSU personnel included two faculty members, five postdoctoral research associates, nine graduate students, and one undergraduate student
