For many-electron atoms (molecules) the calculation of long-range interactions by the variation-perturbation method is ambiguous when the eigenfunction o. describing separate non-interacting atoms is not accurately known. Doubleperturbation theory is suggested as a systematic way of evaluating small

We analyze the divergent contributions to the Hamiltonian for extended, nonmetallic systems in one dimension, to both the ground-state correlation energy and to the correlated band structure. It is shown that the contribution from the long-range divergent part of the Hamiltonian tends to zero as 1rM
The competition between diffusive hops and direct tunnelling of solvated electrons to scavenger molecules in solid glasses has been discussed in the literature\_ We have considered these two reaction paths in terms of stationary kinetic diffusion equations and multiphonon electron-transfer rate theo
The effect of the weak long-range interaction on the shielding constant is considered for a pair of interacting atoms. The asymptotic long-range effects are proportional to R-" (where R is the interatomic distance). For the anisotropy of the shielding tensor n = 3, for the trace n = 6 for two neutra
