Variational calculations of the $\Lambda$-seperation energy of the $_{\Lambda}^{17}$O hypernucleus
Abstract
Variational Monte Carlo calculations have been made for the O hypernucleus using realistic two- and three-baryon interactions. A two pion exchange potential with spin- and space-exchange components is used for the N potential. Three-body two-pion exchange and strongly repulsive dispersive NN interactions are also included. The trial wave function is constructed from pair- and triplet-correlation operators acting on a single particle determinant. These operators consist of central, spin, isospin, tensor and three- baryon potential components. A cluster Monte Carlo method is developed for noncentral correlations and is used with up to four-baryon clusters in our calculations. The three-baryon NN force is discussed.
