Isomer Ratios and Mean Angular Momenta of Primary 97Nb Fragments at 235U and 238U Photofission

Section: Nuclei and Nuclear Reactions
Original Author's Text: Ukrainian

Abstract:  The isomeric yield ratios are measured for 97Nb fragments obtained at the bremsstrahlung photofission of 235U and 238U nuclei with gamma-quantum end-point energies of 10.5, 12.0, and 18.0 MeV. The mean angular momenta of primary fission fragments are determined, by using the generalized Huizenga–Vandenbosh statistical model and with the help of TALYS 1.6 and EMPIRE 3.2 codes.

Key words: photofission, isomeric ratios, mean angular momenta of fission fragments.
