Information × Registration Number 0217U001188, 0112U005132 , R & D reports Title Investigation of fission dynamic of radioactive transuranium nuclei at excitation energies of compaund nuclei near 10-12 МeV. popup.stage_title Head Zheltonozhsky Victor Aleksandrovich, Доктор фізико-математичних наук Registration Date 26-01-2017 Organization Institute For Nuclear Research Of National Academy Of Sciences Of Ukraine popup.description2 New data is obtained about isomeric ratios of 97Nb nuclei which are created as a result of 235U and 238U nuclei photofission for the end point energies of bremmsstrahlung photons about: 10.5, 12.0 and 18 MeV with use the activation techniques and taking into account the contribution to population from an isobar nucleus-predecessor. The difference of values of isomeric ratios is observed at Ee = 10.5 and 12 MeV from Ee = 18 MeV that can testify that isomeric ratios essentially depend on type of the entrance channel. Theoretical values of the average angular moments of photofission fragments are defined with use of TALYS 1.6 and EMPIRE 3.2 codes and possibility is considered of the population of 97Nb states after of the eject till two neutrons after disintegration of primary fragments, with biger, than at 97Nb, quantity of neutrons. Values of the average angular momentums of the primary photofission fragments with and without a departure of neutrons eject coincide within an error. Difference of values of the average angular momentums of photofission fragments from their values in a parent nuclei testifies to presence of the additional mechanism of formation of the angular momentums.
