✦ Synopsis


The two-and three-body correlation energies in liquid 3He are calculated within the framework of Brueckner-Goldstone theory. Various approximations taken from nuclear matter calculations and used in previous liquid helium studies are examined and improved upon.

The dependence of the g-matrix elements on the center of mass momentum of the interacting particles and the question of the self-consistency of the hole spectrum are treated more systematically and extensively than before.

The contribution to the three-body energy of relative partial wave interactions with nonzero relative angular momentum is studied in some detail for the first time.
