Quantum Monte Carlo Calculations of A ≤6 Nuclei

The energies of ³H, ³He, and ⁴He ground states, the 3 / 2^- and 1 / 2^- scattering states of ⁵He, the ground states of ⁶He, ⁶Li, and ⁶Be, and the 3⁺ and 0⁺ excited states of ⁶Li have been accurately calculated with the Green's function Monte Carlo method using realistic models of two- and three-nucleon interactions. The splitting of the A  =  3 isospin T  =  1 / 2 and A  =  6 isospin T  =  1, J^π  =  0⁺ multiplets is also studied. The observed energies and radii are generally well reproduced, however, some definite differences between theory and experiment can be identified.
