N-P Interaction And Signature Inversion

First ,We review the theories given to explain the phenomena about signature inversion. And point out that the PRM model is the base of our work. Subsequently, we introduce some basic knowledge about nuclear structure and signature inversion.Second, Simply introducing the odd-odd nucleus's PRM model and analyze the shortcoming of the PRM.Third party ,Before calculating the N-P interaction ,we introduce the hamonic oscillation's potential and it's energy .At one time ,we give some knowledge about δ interaction ,it is the base to improve Hamiltonian and write program.Forth , On base of calculating the N-P interaction's matrix element ,we import the base vector .then we can diagonalize the matrix with the vector. At the same time ,we point out how to add the new potential in actual calculating.At last ,we research several factors in model , that can affect the ending of calculating .moreover ,we compare the theoretical results with the experiments.
