LArSoft

The larsim MarleyGen module is used to configure the MARLEY supernova neutrino generator for use with LArSoft. In versions v06_04_00 through v06_18_00 of LArSoft, the module loads nuclear structure data (level energies, gamma-ray branching ratios, etc.) into MARLEY, but the events produced using the module fail to use these data. Instead, MARLEY falls back to using a continuum de-excitation model (the Hauser-Feshbach statistical model) for all level energies, including bound states. The command-line MARLEY executable included with LArSoft, however, gives the correct behavior when identical configuration file settings are used.
