Abstract

The surface energy of a semi-infinite system of nuclear matter is calculated using a two-nucleon nonlocal interaction which fits scattering data (the Tabakin interaction). The single-particle wave functions used in the description of the ground state of the system are generated by a velocity-dependent Woods-Saxon potential, whose parameters are varied to find the optimum nuclear energy and thickness. A moderately strong velocity dependence is needed. The potential energy distributes itself over the nuclear volume in a way which depends characteristically on the relative orbital angular momentum of the two-particle states. TheS, P andD waves contribute in the proportion of 6.57:2.75:1 to be compared with their relative contributions 10.02:2.38:1 in infinite nuclear matter.
