A density functional for short-range electron–electron interaction recently developed by one of us, has been implemented into a multi-reference configuration-interaction code with explicit treatment of long-range interaction only. Possible Ž . Ž advantages of such an approach are discussed, using as examples some closed-shell atoms Be, Ne and diatomics H , Li , 2 2 . C , N , F . q 1997 Publishe...

We explore the structural changes in charge the density and the electron configuration of quantum dots caused by the presence of other dots in an array, and the interaction of neighboring dots. We discuss what recent measurements and calculation of the far-infrared absorption reveal about almost isolated quantum dots and investigate some aspects of the complex transition from isolated dots to d...

Dielectronic recombination (DR) of Na-like Fe15+ forming Mg-like Fe14+ via excitation of a 2l core electron has been investigated. We find that configuration interaction (CI) between DR resonances with different captured electron principal quantum numbers n can lead to a significant reduction in resonance strengths for n 5. Previous theoretical work for this system has not considered this form ...

We show the existence of dynamical zeros in the helicity amplitudes for neutrinoelectron elastic scattering at lowest order in the standard theory. In particular, the λ = 1/2 non-flip electron helicity amplitude in the electron antineutrino process vanishes for an incident neutrino energy Eν = me/(4sin θW ) and forward electrons (maximum recoil energy). The rest of helicity amplitudes show kine...

the effect of alkyl substituents on the c-phenyl and/or the n-phenyl ring of benzophenylhydroxamic acid on their molecular structure and hydrogen bonding has been investigated. the predominant configuration in chcl3 is determined by steric and electronic effects. substituents on the c-phenyl ring favor the cis configuration, while substituents in the n-phenyl ring favor a trans configuration. t...

We show that the recombination kinetics of two-dimensional electrons with acceptor bound holes is a sensitive probe of the local spatial structure of the electronic system. Using the time resolved magnetoluminescence, we extract the regime of the electron Wigner solid and establish its local configuration consistent with the triangular lattice model. Up to the melting point, the amplitude of th...
