Nucleon Nucleon Interaction

A phenomenological NN interaction has been developed in momentum space to fit the elastic scattering phase shifts, the deuteron properties and to saturate nuclear matter. The special features of this interaction are gaussian momentum dependent form factors and the use of only three mesons to characterise the phase shifts.

Scattering Phase Shifts

The properties of the Sussex interaction are tested in the study of the n–16O elastic scattering described by the potential scattering in the Hartree–Fock field. This force leads to an easy determination of the self-consistent field, but gives s1/2 and d3/2 phase shifts which are not very satisfactory. This results from the important gap separating bound and unbound states. Further, some uncertainty in the calculation arises from approximations necessary in order to obtain some nondiagonal matrix elements of the two body force which are necessary in the determination of the phase shifts.

Scattering Phase Shifts

The theory given by Rudge (1970) is reformulated and a set of coupled differential equations solved to yield elastic scattering phase shifts and XS partial inelastic cross-sections. The convergence is studied as the size of the basis set is increased and results compared with other theoretical data. It is concluded that the method is a successful one though there remain problems which require further study.
