The effect of dynamical short-range correlations on the generalized momentum distribution n(\p,\Q) in the case of Z=N, \ℓ-closed shell nuclei is investigated by introducing Jastrow-type correlations in the harmonic-oscillator model. First, a low order approximation is considered and applied to the nucleus 4He. Compact analytical expressions are derived and numerical results are presented for the case that \p is parallel to \Q. Next, an approximation is proposed for n(\p, \Q) of heavier nuclei, that uses the above correlated n(\p,\Q) of 4He. The quality of both approximations is evaluated. Results are presented for the nucleus 16O in the case of \p parallel to \Q. It is found that the effect of short-range correlations is significant for rather large values of the momenta p and/or Q and should be included in a reliable evaluation of n(\p,\Q) in the whole domain of p and Q.
