Implementation of residual nucleus de-excitations associated with proton decays in $^{12} {\rm C}$ based on the GENIE generator and TALYS code

TL;DR

This paper enhances the modeling of residual nucleus de-excitations linked to proton decays in carbon-12 by integrating GENIE and TALYS, improving agreement with experimental data.

Contribution

It introduces a modified GENIE generator with a Spectral Function model and combines it with TALYS for better de-excitation process simulation.

Findings

TALYS calculations partly match experimental data.

Modified GENIE provides more realistic excitation energy spectra.

Improved modeling aids in understanding proton decay residuals.

Abstract

We implement the de-excitation processes of residual nuclei associated with proton decays in $^{12} {\rm C}$ based on the GENIE generator and TALYS code. To derive the reasonable excitation energy spectra of residual nuclei $^{11} {\rm B}$, $^{10} {\rm B}$ and $^{10} {\rm Be}$, the default GENIE nucleon decay generator is modified in terms of the Spectral Function nuclear model. Then we use the TALYS code to estimate the de-excitation processes of residual nuclei. The TALYS calculation can partly account for the experimental data.
