The simulation of gamma spectra of 113Cd(n,γ) for neutron resonance spin assignment

The gamma decay of the highly excited nucleus of 114Cd, formed by neutron capture, has been simulated numerically. The intensity of transitions between low-lying states was found to be dependent on the neutron resonance spin, as expected from the low-level population spin assignment method. The simulations are in excellent agreement with recent measurements of neutron p-wave resonance spin assignments in 113Cd. The simulations support the work of spin assignment necessary for the interpretation of parity nonconservation measurements.
