Аннотация:Theoretical cross sections of the neutron capture reaction on neutron-rich isotopes 180−190Tb have been obtained using the TALYS statistical model with various methods of calculating nuclear masses and energy level densities. On the basis of these data, reaction rates at a temperature of 1.2 GK corresponding to the explosive evolution of a star have been computed. The obtained rates were used to calculate the astrophysical 𝑟-process using the SkyNet Modular Nuclear Reaction Network Library. Concentrations deviations of 𝑟-process products were computed for different parameters of the statistical model for calculating cross sections.
