$^{240}$ Pu的PDKEEPAAA与还原态密度泛函理论

Fission of $^{240}$Pu with symmetry-restored density functional theory

Petar Marević, Nicolas Schunck

摘要:

核裂变在从天体物理学到核工程的基础科学和应用科学中发挥着重要作用,但它仍然是对核理论的重大挑战。到目前为止,用于计算裂变可观测量的理论方法依赖于破缺方案,其中丢失了关于裂变核的粒子数、角动量和宇称的基本信息。在这项工作中,我们分析了恢复破坏对称性的基准情况下,$^{240}$钚的影响。

英文摘要:

Nuclear fission plays an important role in fundamental and applied science, from astrophysics to nuclear engineering, yet it remains a major challenge to nuclear theory. Theoretical methods used so far to compute fission observables rely on symmetry-breaking schemes where basic information on the number of particles, angular momentum, and parity of the fissioning nucleus is lost. In this work, we analyze the impact of restoring broken symmetries in the benchmark case of $^{240}$Pu.
