- Abstract
- The photo-fission yields and photo-neutron cross-sections of (gamma, 3n) and (gamma, 4n) on Bi-209 induced by 50 and 65 MeV bremsstrahlung have been measured by using a recoil catcher and an off-line gamma-ray spectrometric technique. The mass-yield distribution of fission products in Bi-209 induced by bremsstrahlung photons from the present work and literature data in the energy range 28-85 MeV is symmetric around 103 mass units. However, the full width at half maximum of the yields distribution increases from 19 mass units at 28-40 MeV to 23 mass units at 85 MeV. The (gamma, 3n) reaction cross-section in the 50 MeV and the (gamma, 4n) reaction cross-section in the 50 and 65 MeV bremsstrahlung-induced reaction of Bi-209 were determined for the first time.
