Isoscaling and fission modes in the yields of the Kr and Xe isotopes from photofission of actinides

Yields of Kr and Xe isotopes in photofission of ²³²Th, ²³⁸U, ²³⁷Np, ²⁴⁴Pu, ²⁴³Am, and ²⁴⁸Cm were tested for isoscaling dependence. Isoscaling for Kr is revealed. For Xe, isoscaling is found to be affected by the STI and STII fission modes governed by the N = 82 and N = 88 neutron shells. The work was performed at the Flerov Laboratory of Nuclear Reactions, Joint Institute for Nuclear Research (JINR).
