Abstract
Quantum Monte Carlo calculations using realistic two- and three-nucleon
interactions are presented for nuclei with up to ten nucleons. Our
Green's function Monte Carlo calculations are accurate to ~1-2%
for the binding energy. We have constructed Hamiltonians using
the Argonne
v18
NN interaction and reasonable three-nucleon
interactions that reproduce the energies of these nuclear states
with only ~500 keV rms error.
Other predictions, such as form factors, decay rates, and spectroscopic
factors also agree well with data.
Some of these results are presented to show that ab initio calculations
of light nuclei are now well in hand.
