# VMC Spectroscopic Overlaps

## Part II: Stripping Reactions

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:

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).

More details of the wave function construction can be found in

Wiringa, Phys. Rev. C **43**, 1585 (1991) for A=3,4;

Pudliner, *et al.*, Phys. Rev. C **56**, 1720 (1997) for A=6,7;

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:

S.F. = Integral ( A^{2}(r) r^{2} dr ) .
Momentum-space amplitudes are available upon request.

In the following, states are designated by ^{A}Z(J^{π};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
^{A}Z(J^{π}_{2};T).
