Studying the Population of 178m,177Ta in (γ, xn) Reactions

The weighted average yields for 177,178mTa in (γ, xn) reactions have been measured for the first time at the 20, 40, and 55 MeV boundary energies of bremsstrahlung γ-quanta. Simulation results using the TALYS-1.9 program code demonstrate the dominance of statistical processes.
