Excitation Functions of Proton-Induced Reactions on 209Bi up to 200 Mev

Pawan Kumar, Sneh Lata Goyal, P K Sarkar

Abstract


The excitation functions of 209Bi(p,n)209Po and 209Bi(p,2n)208Po  reactions  for the production of radio nuclides 208,209Po were evaluated by nuclear model calculations in the 1-200 MeV energy range. The nuclear model codes used for these reactions are ALICE-91, EMPIRE-3.1 and TALYS-1.8. The codes deal with three major nuclear reaction mechanisms including, direct, pre-equilibrium and compound reaction mechanism. The computed excitation functions of these reactions have been compared graphically with available experimental data and the evaluated nuclear data files.


Keywords
