The transition rates for 232 Th using the two component particle-hole state density with different corrections

الملخص

The particle-hole state densities have been calculated for Th in the case of incident neutron with T=Tz, Tz+1, and Tz+2. The finite well depth, surface effect, isospin and Pauli correction are considered in the calculation of the state densities and then the transition rates. The isospin correction function f iso has been examined for different exciton configurations and at different excitation energies up to 100 MeV. The present results are indicated that the included corrections have more affected on transition rates behavior for lamda pi plus, lamda nu plus, lamda pi nu, and lamda nu pi above 30MeV excitation energy.
