Project Description

We studied the neutron-rich isotope 42Si using inverse-kinematics proton scattering from a liquid hydrogen target at the Facility of Rare Isotope Beams at Michigan State University. We utilized a supercomputer to run multiple Geant4 simulations and fit them to our measured gamma-ray spectrum. The simulated spectrum is used to find the energy and half-life of the first excited state. We deduced inelastic-scattering cross-sections using the Gretina gamma-ray tracking array. Our results provide a sensitive test of shell-model descriptions of the evolution of the N=28 shell below 48Ca.
