Quantum Monte Carlo for light nuclei Original Research Article

Quantum Monte Carlo calculations using realistic two- and three-nucleon interactions are presented for nuclei with up to nine nucleons. Our Greens function Monte Carlo calculations are accurate to ∼1% 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.
