$\mathtt{\text{nrCascadeSim}}$ -- A simulation tool for nuclear recoil cascades resulting from neutron capture

Neutron capture-induced nuclear recoils have emerged as an important tool for detector calibrations in direct dark matter detection and coherent elastic neutrino-nucleus scattering (CE$\nu$NS). $\mathtt{\text{nrCascadeSim}}$ is a command-line tool for generating simulation data for energy deposits resulting from neutron capture on pure materials. Presently, silicon, germanium, neon, and argon are supported. While the software was developed for solid state detector calibration, it can be used for any application which requires simulated neutron capture-induced nuclear recoil data.
