Abstract
Fully variational Calculations which employ the Distributed Gaussian Functions (DGF) approach, and an overall potential within each trimer given as a sum of two-body potentials, have been implemented with a new computational scheme and Used to verify the features of bound states in very weakly interacting systems. As test cases, the "half-neon" and the weakly bound bosonic He(3), have been analyzed. The present, very extended expansions are discussed in detail and Our findings are found to compare favorably with the existing results on these systems. (C) 2008 Elsevier B.V.
