Manifestation of the Fission Dynamics in Muon-Induced Prompt Fission

Abstract

In muonic atoms of ²³⁸U, the nuclei can undergo prompt fission through non-radiative transitions of the muon: \(2p{\text{-}}1s\), \(3p{\text{-}}1s\), \(3d{\text{-}}1s\) etc. Main features of the fission dynamics are studied in prompt fission: augmentation of the barrier, dynamics of the saddle-to-scission descent, muonic conversion and characteristic X-rays from fission fragments supply many-lateral information on the fission dynamics and properties of the fragments. Revision of the nonradiative transition probabilities promises new information concerning structure of the giant multipole resonances.
