Abstract

An explicit expression for the triplet Feenberg function in r-space is obtained. Making use of this result and employing the variational ansatz the ground state energy of boson 4He trimer, interacting via Lennard-Jones (12-6) pair potential, is evaluated. The 4He trimer is considered because it includes triplet Feenberg correlations in the simplest form. It is shown that the binding energy is not improved after the inclusion of the triplet Feenberg function. In addition, the applicability of the approximation of averaging over equal interatomic distances is also discussed.
