[en] Studying anomalous manifestations in mass spectra of nucleon-nucleon interactions and especially searching of dibaryon resonance states are actual problem for physicists theoreticians and experimenters. Recently at physics centers of CIS (Former SU), France, Germany, USA and Japan quite a number of experiments have been fulfilled in order to observe the resonances in two-nucleon systems. But their results are controversial. On the one hand they indicate to existence of dinucleon resonances in a large region of effective mass (from sum of two nucleon mass to ∼2,9 GeV), but on the other hand there are experiments, which certainly do not confirm existence of such structures in M_pp-spectra of NN systems. Solutions of problem implies hard requirements to experiment: high mass resolution, large statistics and the minimal methodological limitations. For searching of diproton structures in mass spectra from A(p,2p)X reactions at E_p=500 MeV two-arm multidetector scintillation spectrometer has been developed and designed by us. This one has both a high full acceptance (∼0,2 sr) and a mass-resolution (∼4 MeV). Preliminary experimental data on mass distributions from Cu(p,2p)X reaction have been obtained. Spectrum analysis demonstrates, that the displayed anomalies may not have statistical origin, and are probably related to dinucleon formation. (author)

[en] On the basis of Planck formula of black body radiation and experimental excitation functions of (p,n) and (p,2n) reactions, an empirical systematics formula is presented, which includes two adjustable parameters, incident proton energies from threshold to 150 Mev, target masses from 44 to 243, and reproduces excitation functions of (p,n) and (p,2n) reactions well

[en] Based on the relevant experimental data of Re and neighbor nucleus W, and the theoretical model calculations, neutron induced reaction cross sections, the energy spectrum, angular distribution, double differential cross section and γ-production data were calculated for ^185,187,NatRe at incident neutron energies below 20 MeV. The calculated results were compared with experimental data

[en] Based on the relevant experimental data, and optical model, evaporation model, Jπ-dependent exciton model, and the pick-up mechanism of cluster pre-formation, neutron induced reaction cross sections, the energy spectrum, angular distribution, double differential cross section and γ-production data were calculated for ⁶³Cu at incident neutron energies below 20 MeV. The calculated results were compared with experimental data

[en] Ni is a very important structure material in nuclear fusion engineering. The natural nickel consists of five stable isotopes. The neutron nuclear data were evaluated for ^{58,60,61,62,64,Nat}Ni in the energy range 10^-5 eV to 20 MeV. The data includes total, elastic, non-elastic, total inelastic, inelastic cross sections to 33 discrete levels, inelastic continuum, (n,2n), (n,3n), (n,n'α) + (n,αn'), (n,n'p) + (n,pn'), (n,p), (n,d), (n,t), (n,α), (n,2p) and capture cross sections. The angular distributions of secondary neutron, the double differential cross sections (DDCS), the gamma-ray production data and the resonance parameters are also included. The evaluation is based on both experimental data measured up to 1995 and calculated data with program UNF. The evaluated data will be adopted into CENDL-3 in ENDF/B-6 format

[en] For analyzing the decay and build-up characteristics of spallation products, the DCHAIN-SP code has been developed on the basis of the DCHAIN-2 code by revising the decay data and implementing the neutron cross section data. The decay data are newly processed from the data libraries of EAF 3.1, FENDL/D-1 and ENSDF. The neutron cross section data taken from FENDL/A-2 data library are also prepared to take account of the transmutation of nuclides by the neutron field at the produced position. The DCHAIN-SP code solves the time evolution of decay and build-up of nuclides in every decay chain by the Beteman method. The code can estimate the following physical quantities of produced nuclides: inventory, activity, decay heat by the emission of α, β and γ-rays, and γ-ray energy spectrum, where the nuclide production rate estimated by the nucleon-meson transport code such as NMTC/JAERI97 is used as an input data. This paper describes about the function, the solution model and the database adopted in the code and explains how to use the code. (author)

[en] The realistic shell model which includes the coupling between many-particle (quasi-)bound states and the continuum of one-particle scattering states is applied to the spectroscopy of mirror nuclei: ⁸B and ⁸Li, as well as to the description of low energy cross sections (the astrophysical S factors) in the capture reactions: ⁷Be(p,γ)⁸B and ⁷Li(n,γ)⁸Li.

[en] The PSIMECX library contains calculated nuclide production cross-sections from neutron-induced reactions in the energy range about 2 to 800 MeV in the following 72 stable isotopes of 24 elements: ¹²C, ¹³C, ¹⁶O, ¹⁷O, ¹⁸O, ²³Na, ²⁴Mg, ²⁵Mg, ²⁶Mg, ²⁷Al, ²⁸Si, ²⁹Si, ³⁰Si, ³¹P, ³²S, ³³S, ³⁴S, ³⁶S, ³⁵Cl, ³⁷Cl, ³⁹K, ⁴⁰K, ⁴¹K, ⁴⁰Ca, ⁴²Ca, ⁴³Ca, ⁴⁴Ca, ⁴⁶Ca, ⁴⁸Ca, ⁴⁶Ti, ⁴⁷Ti, ⁴⁸Ti, ⁴⁹Ti, ⁵⁰Ti, ⁵⁰V, ⁵¹V, ⁵⁰Cr, ⁵²Cr, ⁵³Cr, ⁵⁴Cr, ⁵⁵Mn, ⁵⁴Fe, ⁵⁶Fe, ⁵⁷Fe, ⁵⁸Fe, ⁵⁸Ni, ⁶⁰Ni, ⁶¹Ni, ⁶²Ni, ⁶⁴Ni, ⁶³Cu, ⁶⁵Cu, ⁶⁴Zn, ⁶⁶Zn, ⁶⁷Zn, ⁶⁸Zn, ⁷⁰Zn, ⁹²Mo, ⁹⁴Mo, ⁹⁵Mo, ⁹⁶Mo, ⁹⁷Mo, ⁹⁸Mo, ¹⁰⁰Mo, ¹²¹Sb, ¹²³Sb, ²⁰⁴Pb, ²⁰⁶Pb, ²⁰⁷Pb, ²⁰⁸Pb, ²³²Th and ²³⁸U. The energy range covers essentially all transmutation channels other than capture. The majority of the selected elements are main constituents of normal materials of construction used in and around accelerator facilities and the library is, first and foremost, designed to be a tool for the estimation of their activation in wide-band neutron fields. This third report describes and discusses the calculational methods used for the heavy nuclei. The library itself has been described in the first report of this series and the treatment for the medium and light mass nuclei is given in the second. (author)
