Abstract: | The structures and distributions of light nuclei are investigated within a microscopic correlation model. Two particle correlations
are responsible for the scattering of model particles either to low momentum- or to high momentum-states. The low momentum
states form the model space while the high momentum states are used to calculate the G-matrix. The three and higher order
particle correlations do not play a role in the latter calculation especially if the correlations induced by the scattering
operator are of sufficient short range. They modify however, via the long tail of the nuclear potential, the Slater determinant
of the (A) particles by generating excited Slater’s determinants.
