Study on (n,2n) and (n,p) reactions of strontium nucleus

The cross sections for (n,2n) and (n,p) nuclear reactions on Sr-84,Sr-86,Sr-88,Sr-90 target nuclei up to 30 MeV from threshold have been investigated. The determination of the cross sections has been done employing the codes ALICE/ASH, PCROSS, CEM03.01 which taking into consideration compound and precompound emissions. Calculations have been performed by using the Weisskopf Ewing model (WEM) of compound reaction mechanism, and the Hybrid model (HM), Geometry Dependent Hybrid model (GDHM) and Full Exciton model (FEM) of precompound reaction mechanism, and Cascade Exciton model (CEM) including Cascade interactions, and the empirical and semi-emipirical systematics. In order to test the theoretical nuclear models, the data obtained from the excitation function calculations are discussed and compared with available experimental values, ENDF/B-VII.1 and TENDL-2014 libraries. Finally the new cross section results calculated in the present paper may be useful for nuclear energy applications. (C) 2015 Elsevier B.V. All rights reserved.
