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

#### Abstract

The excitation functions of ^{209}Bi(p,n)^{209}Po and^{ 209}Bi(p,2n)^{208}Po reactions for the production of radio nuclides ^{208,209}Po 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.
