This web page presents recent spectroscopic overlaps calculated for a variety of nuclei in the range A=3-12. 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) or the Norfolk Δ-full chiral effective field theory interactions NV2+3-Ia, -Ia*, and -IIb*.
A number of these results have served as input to papers on specific reactions, including:
Mecca, et al., Phys. Lett. B 798, 134989 (2019);
Crespo, et al., Phys. Lett. B 803, 135355 (2020);
Cravo, et al., Phys. Lett. B 859, 139087 (2024).
These VMC wave functions are the starting trial functions for a
number of recent Green's function Monte Carlo (GFMC) calculations:

McCutchan, et al., Phys. Rev. C 86, 024315 (2012);
Pastore, et al., Phys. Rev. C 87, 035503 (2013);
Pastore, et al., Phys. Rev. C 90, 024321 (2014).

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).
