2 6 Se p 19 97 Bound States and Scattering Processes in the 4 He 3 Atomic System

We present a mathematically rigorous method for solving three-atomic bound state and scattering problems. The method is well suited for applications in systems where the inter-atomic interaction is of a hard-core nature. It has been employed to obtain the groundand excited-state energies for the Helium trimer and to calculate, for the first time, the scattering phase shifts and wave-functions f...

O ct 1 99 9 Investigation of 4 He 3 trimer on the base of Faddeev equations in configuration space

Binding Energies and Scattering Observables in the 4 He 3 Atomic System ∗

There is a great number of experimental and theoretical studies of the He three-atomic system (see, e. g., [1–9] and references cited therein). Most of the theoretical investigations consist merely in computing the bound states, while scattering processes found comparatively little attention. In Ref. [10] the characteristics of the He–He2 scattering at zero energy were studied. The recombinatio...

An optimized full-configuration-interaction nuclear orbital approach to a "hard-core" interaction problem: application to (3He)(N)-Cl2(B) clusters (N < or = 4).

An efficient full-configuration-interaction nuclear orbital treatment has been recently developed as a benchmark quantum-chemistry-like method to calculate ground and excited "solvent" energies and wave functions in small doped DeltaE(est) clusters (N < or = 4) [M. P. de Lara-Castells, G. Delgado-Barrio, P. Villarreal, and A. O. Mitrushchenkov, J. Chem. Phys. 125, 221101 (2006)]. Additional met...

Ground state of small mixed helium and spin-polarized tritium clusters: a quantum Monte Carlo study.

We report results for the ground-state energy and structural properties of small (4)He-T↓ clusters consisting of up to four T↓ and eight (4)He atoms. These results have been obtained using very well-known (4)He-(4)He and T↓- T↓ interaction potentials and several models for the (4)He- T↓ interatomic potential. All the calculations have been performed with variational and diffusion Monte Carlo me...
