Short-range correlations in nuclei are considered on a unitary-model operator approach. Short-range pseudopotentials have been added to achieve healing in the correlated wave functions. With the introduction of the pseudopotentials, correlated basis wave functions are constructed. The matrix element for effective interaction in nuclei is developed. The required pseudopotentials have been calculated for the Hamada-Johnston, Yale and Reid potentials and for the nuclear nucleon-nucleon potentialA calculated by us according to meson exchange between nucleons.
