The wcond-order energy for Ne is computed starting with the symmetric sum of oneclectron Hartree-Fock operators as the Teroth-ordcr hamiltonian. The variational-perturbation pair functions of dcfmite orbital and spin symmetry are expressed in the form of partial wave expansions. Special attention is

The second-order connected moments expansion (CMX( 2)) approach to calculation of the correlation energy is tested numerically on several closed-shell di-and tri-atomic molecules. Benchmark computations performed within 6-31G\*\* basis set reveal that CMX( 2) usually recovers more than SO?+ of the M
The pump-and-probe response of a ZnSe quantum well is investigated. In this particular sample the binding energy far exceeds both the exciton damping and the inhomogeneous broadening. A comparison between experimental data and model calculations shows that with co-circularly polarized beams the nonl
