# Fission dynamics of $^{252}$Cf

## TL;DR

This paper applies the TDGCM+GOA formalism to model the fission of $^{252}$Cf, analyzing how initial states and propagation time affect fragment mass distributions, with results compared to experimental data.

## Contribution

The study introduces a detailed application of TDGCM+GOA to $^{252}$Cf fission, exploring initial state effects and propagation time on mass yields, which enhances understanding of fission dynamics.

## Key findings

- Mass yields show weak dependence on initial conditions.
- Calculated distributions agree with experimental data.
- Propagation time influences the final fission fragment distributions.

## Abstract

The time-dependent generator coordinate method with the gaussian overlap approximation (TDGCM+GOA) formalism is applied to describe the fission of $^{252}$Cf. We perform analysis of fission from the initial states laying in the energetic range from the ground state to the state located 4 MeV above the fission barrier. The fission fragment mass distributions, obtained for different parity, energy of levels and types of mixed states, are calculated and compared with experimental data. The impact of the total time of wave packet propagation on the final results is studied as well. The weak dependence of obtained mass yields on the initial conditions is shown.
