This web page presents recent spectroscopic overlaps calculated for a variety of nuclei in the range A=3-10 with some preliminary results for A=11,12. Corresponding one-nucleon densities can be found here. These are from variational Monte Carlo calculations (VMC) using the Argonne v18 two-nucleon and Urbana X three-nucleon potentials (AV18+UX). (Urbana X is intermediate between the Urbana IX and Illinois-7 models; it has the form of UIX supplemented with a two-pion S-wave piece, while the strengths of its terms are taken from the IL7 model. It does NOT have the three-pion-ring term of IL7.)
These VMC wave functions are the starting trial functions for a
number of recent Green's function Monte Carlo (GFMC) calculations:

Wiringa, et al., Phys. Rev. C 62, 014001 (2000) for A=8;
Pieper, et al., Phys. Rev. C 70, 044310 (2002) for A=9,10.
Following are figures and tabulations of the single-nucleon r-space amplitudes A(r) (in fm-3/2) and the integrated spectroscopic factors with the normalization:
Momentum-space amplitudes are available upon request.
In the following, states are designated by AZ(Jπ;T) except the T is omitted for states of the lowest isospin available to that nucleus. Second excited states of the same quantum numbers are denoted by AZ(Jπ2;T).
