Photodisintegration of tantalum

The yields of photonucleon reactions on the isotope 181Ta that are induced by bremsstrahlung photons whose endpoint energy is 67.7 MeV are measured by the residual-activity method. The cross sections for photonucleon reactions on the isotope 181Ta are calculated on the basis of the TALYS code and a combined model. The measured reaction yields are compared with their counterparts rescaled from cross sections obtained in experiments that employed beams of quasimonochromatic and bremsstrahlung photons. The spectra of neutrons emitted from 181Ta nuclei after the absorption of photons having various energies are calculated within the TALYS code and the combined model in question.
