Microscopic Study on Induced Fission Dynamics of 258Fm within Covariant Density Functional Theory by CHEN Shengyuan;LI Zeyu;CHEN Yongjing;LI Zhipan

“…In recent years, nuclear fission attracts more attention due to the following reasons: Nuclear fission plays a crucial role in determining the stability of superheavy elements, and is one of the primary mechanisms that terminate nucleosynthesis and determine the abundance of the synthesized nuclides; It is also an important mechanism used to produce shortlived exotic nuclides and fission of exotic nuclei far from stability also provides a new and effective way to study exotic nuclei. …”
