[en] The proton momentum and density distributions of closed shell nuclei are calculated with a model treating short-range correlations up to first order in the cluster expansion. The validity of the model is verified by comparing the results obtained using purely scalar correlations with those produced by finite nuclei Fermi hypernetted chain calculations. State dependent correlations are used to calculate momentum and density distributions of ¹²C, ¹⁶O, ⁴⁰Ca, and ⁴⁸Ca, and the effects of their tensor components are studied. copyright 1997 The American Physical Society
