# The effect of the Landau--Zener transitions on nuclear fission dynamics

## TL;DR

This paper investigates how Landau-Zener transitions between nuclear states influence nuclear fission dynamics, particularly focusing on dissipation and fission rates at high temperatures using a cranking-like approach.

## Contribution

It introduces a self-consistent method to analyze the impact of spectral statistics on nuclear fission, incorporating Landau-Zener transitions into the modeling of large-amplitude collective motion.

## Key findings

- Landau-Zener transitions significantly affect dissipation in nuclear fission.
- Spectral statistics influence the fission rate at high initial temperatures.
- The approach provides insights into the microscopic mechanisms of nuclear energy dissipation.

## Abstract

In the paper, it is studied the influence of Landau-Zener transitions between nuclear many-body states on the dissipative properties of nuclear large--amplitude collective motion. Within the cranking-like approach, we describe the time evolution of a nuclear many-body system as the self-consistent motion in a space of intrinsic excitations and in a space of a single collective (deformation) parameter. By that we measure how the spectral statistics of the nuclear energy levels affects the fission rate at quite large initial temperatures of heavy nuclei.
