On Nuclear Structure Effects in the Nucleon‐Induced Fission Cross Sections of Nuclei near ²⁰⁸Pb at Intermediate Energies Available to Purchase

Recently measured energy dependences of fission cross sections of lead isotopes ^{204,206–208}Pb at incident nucleon energies up to 180 MeV were analyzed. Regularities were established of the fission cross‐section variation with the mass number of isotopes pointing to incomplete dumping of shell effects even at nucleon energies 150–180 MeV. The fission cross sections of lead isotopes, assumed as spherical nuclei, are compared with those of deformed nuclei. The experimental data are compared with calculations by the code TALYS.
