In this study, reactions induced by electrons with energies ranging from 20 to 110 MeV were investigated by measuring residual gamma-ray activities, in order to study the Coulomb excitation-induced nuclear reaction. The experiments measured cross sections for 181Ta(
)181−xTa reactions. Notably, this study reports, for the first time, (
) cross-section data for reactions with incident electrons’ energy higher than 30 MeV. Comparisons between the measured cross sections and theoretical values calculated by TALYS2.0 code revealed significant discrepancies. Possible sources of these discrepancies are discussed, including transmission coefficients as well as nuclear-level densities.
