  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.
