Query: Deuteron Distribution in Nuclei and in Correlated Nuclear Matter   We compute the distribution of quasideuterons in doubly closed shell nuclei
and infinite correlated nuclear matter. The ground states of $^{16}$O and
$^{40}$Ca are described in $ls$ coupling using a realistic hamiltonian
including the Argonne $v_{8}^\prime$ and the Urbana IX models of two-- and
three--nucleon potentials, respectively. The nuclear wave function contains
central and tensor correlations, and correlated basis functions theory is used
to evaluate the distribution of neutron-proton pairs, having the deuteron
quantum numbers, as a function of their total momentum. By computing the number
of deuteron--like pairs we are able to extract the Levinger's factor and
compare to both the available experimental data and the predictions of the
local density approximation, based on nuclear matter estimates. The agreement
with the experiments is excellent, whereas the local density approximation is
shown to sizably overestimate the Levinger's factor in the region of the medium
nuclei.
