Separation energy dependence of hole form factors in a simple microscopic model

Form factor of fragmented neutron hole states in 207Pb are studied via microscopic calculations in the limiting case of incoherent contributions of hole coupling with two hole one particle states. The calculations were performed using the inhomogeneous equation method with a Serber-exponential nucle...

description Form factor of fragmented neutron hole states in 207Pb are studied via microscopic calculations in the limiting case of incoherent contributions of hole coupling with two hole one particle states. The calculations were performed using the inhomogeneous equation method with a Serber-exponential nucleon nucleon effective force. Large fluctuations of form factor radii deduced for individual levels are observed. The role of the level configurations and of the nucleon nucleon force parameters are discussed in details in the case of g_7/2 inner hole fragments. The underlying dependences of form factor radii on separation energy deduced for the different valence and inner hole states are found much smaller than predicted in the framework of the quasiparticle- phonon model(QPM).
