摘要
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 similar to1-2% for the binding energy. We have constructed Hamiltonians using the Argonne v(18) NN interaction and reasonable three-nucleon interactions that reproduce the energies of these nuclear states with only similar to500 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.
