Exploring the Role of Nuclear Structure Effects in Photofission Mechanism of 237Np

Abstract

Abstract: The photofission which is very important for various nuclear applications involves the excitation and subsequent fission of a nucleus by photon absorption. This study explores the complexities of 237Np photofission, highlighting the critical roles of nuclear level density at saddle points and fission barrier parameters. Using advanced theoretical models and nuclear reaction codes, the research investigates the interplay between these factors and the photofission cross sections of 237Np. Theoretical results are compared with experimental data to deepen our understanding of photofission dynamics. © Pleiades Publishing, Ltd. 2025.
