We report variational calculations, in the HNC/FHNC scheme, of one-body density matrices and one-particle momentum distributions for /sup 3/He-/sup 4/He mixtures described by a Jastrow correlated wave function. The /sup 4/He condensate fractions and the /sup 3/He strength poles are examined and compared with the Monte Carlo available results. The agreement has been found very satisfactory. The density dependence is also studied.
