class NuclearDecay : public Module

Nuclear decay of unstable nuclei.

This module simulates the nuclear decay of unstable nuclei using data from NuDat2. All decay modes are considered: alpha, beta+- and gamma decay, as well as proton- and neutron dripping. The resulting non-hadronic secondary particles (e+, e-, neutrinos, gamma) can optionally be created.

For details on the preprocessing of the NuDat2 data refer to “CRPropa3-data/”.
