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

Abstract

We implement the de-excitation processes of residual nuclei associated with proton decays in ${}^{12}\mathrm{C}$ based on the GENIE generator and TALYS code. To derive the reasonable excitation energy spectra of residual nuclei ${}^{11}\mathrm{B}$, ${}^{10}\mathrm{B}$ and ${}^{10}\mathrm{Be}$, 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.
