# Multi-Nucleon Transfer in Central Collisions of $^{238}$U + $^{238}$U

## TL;DR

This paper investigates the quantum diffusion process of nucleon exchange in central uranium-238 collisions using the stochastic mean-field approach, providing insights into the primary fragment distributions during such nuclear reactions.

## Contribution

It introduces a quantal diffusion model for nucleon exchange in heavy-ion collisions within the SMF framework, accounting for memory effects and maintaining di-nuclear structure.

## Key findings

- Quantal neutron and proton diffusion coefficients are extracted.
- Primary fragment distributions are successfully calculated.
- Memory effects are incorporated into the diffusion process.

## Abstract

Quantal diffusion mechanism of nucleon exchange is studied in the central collisions of $^{238}$U + $^{238}$U in the framework of the stochastic mean-field (SMF) approach. For bombarding energies considered in this work, the di-nuclear structure is maintained during the collision. Hence, it is possible to describe nucleon exchange as a diffusion process for mass and charge asymmetry. Quantal neutron and proton diffusion coefficients, including memory effects, are extracted from the SMF approach and the primary fragment distributions are calculated.
