# Probing nuclear bubble configuration by proton induced reaction

## TL;DR

This paper investigates how proton-induced reactions can be used to detect bubble configurations in the hypothetical $^{48}$Si nucleus, revealing distinct proton emission patterns that serve as indicators.

## Contribution

It introduces a novel method using proton reactions at 0.8 GeV/nucleon to probe nuclear bubble structures, based on transport model simulations.

## Key findings

- More energetic protons emitted along the beam direction with bubble configuration.
- Fewer scattered energetic protons at forward angles with bubble configuration.
- Proposes a new experimental approach to identify nuclear bubbles.

## Abstract

In the framework of the isospin-dependent Boltzmann-Uehling-Uhlenbeck transport model, nuclear bubble configuration in the hypothetical $^{48}$Si nucleus is studied by proton induced central reaction at an incident beam energy of 0.8 GeV/nucleon. It is found that along the beam direction more energetic protons are emitted with bubble configuration in the target. In the forward angles, compared with the case without bubble configuration, less scattered energetic protons are emitted with bubble configuration in the target. We thus provide a new way to probe the bubble configuration in nuclei.
