Thomas-Fermi theory is developed to evaluate nuclear matrix elements on the average. One and two body matrix elements are compared with quantal results and it is demonstrated that the semiclassical matrix elements nicely follow the quantal values on the mean. Various physical situations are ad-dresed where the semiclassical evaluation of the one and two body matrix elements can be useful.

Thomas-Fermi theory is developed to evaluate nuclear matrix elements averaged on the energy shell, on the basis of independent particle Hamiltonians. Oneand two-body matrix elements are compared with the quantal results and it is demonstrated that the semiclassical matrix elements, as function of energy, well pass through the average of the scattered quantum values. For the one-body matrix elem...

متن کاملNuclear G-Matrix Elements from Nonlocal Potentials
We study effects of nonlocality in the nuclear force on the G-matrix elements for finite nuclei. Nuclear G-matrix elements for 16O are calculated in the harmonic oscillator basis from a nonlocal potential which models quark exchange effects between two nucleons. We employ a simple form of potential that gives the same phase shifts as a realistic local nucleon potential. The G-matrix elements ca...
