To test this, calculations of the theoretical reaction cross sections of 85Rb( ; n)88Y , 85Rb( ; 2n)87Y , 85Rb( ; 3n)86Y and composition reaction of 85Rb( ; n) and 87Rb( ; 3n) reactions are car- ried out in the incident alpha energy from 15 MeV to 60 MeV. Theoretical calcula- tions of reaction cross sections are done using Alice-91 computer code, which is based on Weisskopf-Ewing model for compound nucleus decay and Geometry Dependent Hybrid (GDH) model for pre-compound nuclear reactions. The calculated results are compared with experimental one and various parameters were changed to see their e ects on the reaction cross sectionsenCompound Nucleus DecayCompound Nucleus Decay of Some Rubidium Systems at Various EnergiesThesis
