Evaluation of Cross Sections for Neutrons and Protons up to 200 MeV on Silicon Isotopes

Abstract

Neutron and proton nuclear data of ^{28, 29}, ³⁰Si for energies from 20 MeV to 200 MeV are evaluated for various nuclear engineering applications. The soft rotator model and the coupled-channels method are used to perform a consistent analysis of the collective band structure and nucleon scattering data. The GNASH nuclear model code is used for compound and preequilibrium particle emission calculations including neutron, proton, deuteron, triton, ³ He, and α-particle. The evaluated results are compared with various experimental data and the LA 150 evaluation.
