Excited states of4Hedroplets
2001
Physical Review B (Condensed Matter)
We study low-lying excited states of 4 He clusters up to a cluster size of 40 atoms in a variational framework. The ansatz wave function combines two-and three-body correlations, coming from a translationally invariant configuration interaction description, and Jastrow-type short-range correlation. We have previously used this scheme to determine the ground-state energies of 4 He and 3 He clusters. Here we present an extension of this ansatz wave function having a good quantum angular momentum
