Studies of one-body density matrices (ODM) are performed in various correlation methods, such as the Jastrow method, the correlated basis function method, the Green's function method and the generator coordinate method aiming to extract the absolute spectroscopic factors and overlap functions (OF) for one-nucleon removal reactions from the ODM of the target nucleus. The advantage of this method is that it avoids the complicated task of calculating the total nuclear spectral function. The procedure for extracting bound-state OF's has been applied to make calculations of the cross sections of the (e,e′p) reaction on the closed-shell nuclei 16O and 40Ca as well as on the open-shell nucleus 32S consistently (using the same OF's) with the cross sections of (p,d) and (γ,p) reactions on the same nuclei. The analyses of the reaction cross sections and the spectroscopic factors and the comparison with the experimental data show the particular importance of these OF's, since they contain effects of nucleon correlations (short-range and/or long-range) which are accounted for to different extent in the theoretical methods considered.
