reactions were calculated using TALYS-1.95 nuclear code from threshold to 50 MeV by
invoking suitable options for level densities, nucleon-nucleus optical model potentials and
alpha optical model potentials. Statistical factors were used to verify the quality of matching
between theoretical model calculations and the experimental data from the EXFOR
database. The TTY of 211 At calculated using the excitation function of 209 Bi (a, 2n) 211 At …
