Jl. Marin et G. Munoz, VARIATIONAL CALCULATIONS FOR ENCLOSED QUANTUM-SYSTEMS WITHIN SOFT SPHEROIDAL BOXES - THE CASE OF H, H-2(+) HEH2+, Journal of molecular structure. Theochem, 106, 1993, pp. 281-285
The direct variational method is used to study some physical propertie
s of H, H-2(+) and HeH2+ enclosed within soft spheroidal boxes. The gr
ound state energy, polarizability, and pressure are calculated for the
se systems as a function of the size and penetrability of the boxes. T
he results show good agreement when compared with more sophisticated c
alculations.
