Implementation of residual nucleus de-excitations associated with proton decays in 12C based on the GENIE generator and TALYS code

We implement the de-excitation processes of residual nuclei associated with proton decays in C-12 based on the GENIE generator and TALYS code. To derive the reasonable excitation energy spectra of residual nuclei B-11, B-10 and Be-10, 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. (C) 2022 The Author(s).

Automated summary

This study modifies the GENIE nucleon decay generator to simulate the de-excitation processes of residual nuclei associated with proton decays, and uses the TALYS code to estimate these processes, partially validating experimental data.
