Description
Ge-mini, a member of the COHERENT suite of detectors, is an array of high-purity germanium semiconductor detectors designed to measure coherent elastic neutrino-nucleus scattering (CEvNS). In this weak neutral-current interaction, the nuclear form factor is primarily sensitive to the neutron spatial distribution and causes a loss of coherence at higher momentum transfers, which appears as a suppression of the recoil spectrum at higher energies. Using COHERENT's newest Ge-mini result, one of the most precise CEvNS measurements to date, we probe the RMS neutron radius of germanium, as well as its "neutron skin." Analysis of a larger dataset is ongoing, and projections of its expected science reach are presented.
