Abstract

Introduction. The bremsstrahlung of electron accelerators is widely used to study properties of the (²³²Th, ²³⁵U, ²³⁸U, ²³⁷Np, ²³⁹Pu, ²⁴⁰Pu, ²⁴¹Am) actinides nuclei photofission products.
Purpose. An approach that allows to adapt the GEF- code to simulate the yields of the products of the photofission of actinide nuclei is proposed.
Results. A simulation of the bremsstrahlung spectrum of the microtron M-30 at electron energies of 8,5 ÷ 20 MeV was carried out. The calculations of the excitation energy have been made for the fissioning nuclei ²³²Th, ²³⁵U, ²³⁸U, ²³⁷Np, ²³⁹Pu, ²⁴⁰Pu, ²⁴²Pu, ²⁴¹Am. The modeling of photofission product yields of nuclei ²³²Th, ²³⁵U, ²³⁸U, ²³⁷Np, ²³⁹Pu, ²⁴⁰Pu, ²⁴²Pu, ²⁴¹Am with the use of GEF-code was carried out.
Conclusion. Calculated outputs of photo-division of nuclear actinides coincide with estimated experimental data within the bounds of errors for the energy domain semen section
