# Induced fission of 240Pu

## TL;DR

This paper investigates the fission process of 240Pu using advanced density functional theory, highlighting the importance of pairing correlations and revealing a slower evolution than previously thought due to a comprehensive, non-adiabatic approach.

## Contribution

It introduces a fully non-adiabatic, symmetry-unrestricted DFT method for modeling 240Pu fission dynamics, emphasizing the role of pairing correlations.

## Key findings

- Fission evolution is slower than earlier models predicted.
- Pairing correlations significantly influence the fission process.
- All collective degrees of freedom are active in the dynamics.

## Abstract

We study the fission dynamics of 240Pu within an implementation of the Density Functional Theory (DFT) extended to superfluid systems and real-time dynamics. We demonstrate the critical role played by the pairing correlations. The evolution is found to be much slower than previously expected in this fully non-adiabatic treatment of nuclear dynamics, where there are no symmetry restrictions and all collective degrees of freedom (CDOF) are allowed to participate in the dynamics.
