Faddeev Monte-Carlo calculations of trinucleon binding energy with three-body potentials

Abstract

Monte Carlo integrations for binding energy and other expectation values in 3H and 3He using configuration-space Faddeev wavefunctions are reported. Nine combinations of two- and three-nucleon potentials are tested, several givin a significant contribution of ∼ Mev to the binding energies from the three-nucleon potentials. The energy contribution of the three-nucleon potential is found to be very sensitive to form factor parameters and to small components of the Faddeev wavefunction. The influence of the three-nucleon potential on the wavefunction is investigated using a simple one-parameter variation of the Faddeev wavefunction.
