Particle-hole level densities in deformed nuclei - art. no. 064311

A microscopic combinatorial approach is used to calculate the state and lev el densities with fixed exciton numbers, in some actinide nuclei. The defor med Woods-Saxon shell model was used as a basis from which all possible con figurations were generated. The pairing interaction was taken into account by applying the BCS theory to each configuration. Both the spin and parity distributions were obtained, considering the deformation of the nucleus. Re levance of the result to parity nonconservation studies involving epitherma l neutrons on U-238 and Th-232 is discussed. [S0556-2813(99)00312-X].
