Geant4 Simulations of Nuclear Isomer Gamma Emission Detection

When an atomic nucleus is excited, it can form a nuclear isomer, a metastable state with a relatively long half-life. By experimentally investigating the energy levels of neutron-rich isomers, nuclear structure models can be better constrained. Using Geant4, Monte Carlo simulations have been performed to determine optimal detector geometry and placement near a target for measurement of nuclear isomer de- excitation via gamma emission. Various beam and target combinations have been simulated. Preliminary results will be presented.
