Project summary

Nowadays several libraries exist in the world of evaluated nuclear data for reactions caused by neutrons. These libraries are intended for works on constructing thermal and fast fission reactors, calculation of shielding, improvement of nuclear weapon, choice of construction materials, creation of medical facilities and other applications. On the other hand, evaluations over reaction cross sections, generated by charged particles, have an extremely limited character and deal first of all with calculations of nuclear-physical processes in hot plasma, taking place in weapon thermonuclear devices. These evaluations enclose mainly thermonuclear reactions of hydrogen and helium isotopes between each other. At the same time the thermonuclear energetic development, creation of testing facilities with both magnetic and inertial plasma confinement demand an expanding of a circle of reactions that could be used during thermonuclear burning. In particular, these is a permanent interest to the application of heavy ions beams such as Li-6,7; B-10,11. The other examples of importance of the data on charged particle interaction with light nuclei are the diagnostics of hot plasma, as well as the consideration of a secondary activity, being developed during a sequential process (charged particle, neutron). Also astrophysical and medical applications demand the expanding of a circle of the evaluated data.

It is supposed during the next 3 years to produce a complete evaluation of cross-sections of proton, deuteron, triton, He-3 and alpha-particle reactions with all light-element targets through O-16 in cooperation with the Nuclear Data Group of Dr. White from LLNL (L-298, P.O. BOX 808, Liver-more, CA 94551, U.S.) and in coordination with the Nuclear Data Section of the IAEA.

It is supposed that there will be not only the integrated reaction cross-sections in the creating evaluated library but angular and energy distribution of its products. Additionally to the evaluated data library applied files will be created, with their help the evaluated data may be simply adapted to the concrete calculated schemes.

During this time the revision of compiled by VNIIEF and LLNL data and the additional compilation of scattered in various literary sources data will be held. For energy intervals where there are no data it is supposed to carry out nuclear-model calculations (for example, using R-matrix theory, optical model, Hauser-Feshbach model). It is supposed to carry out the nuclear reaction cross-section measurements using the available by VNIIEF accelerator EGP-10.

The realization of the Project will be performed by highly qualified specialists having extensive experience in the work of providing of weapon programs by nuclear data and great experimental and calculation base of VNIIEF will be used.
