Effective Electron-Electron Interaction in Organic Chain Molecules

Effective interaction in quasielastic electron scattering calculations

The transverse nuclear response for quasifree electron scattering is discussed. The analysis is done by comparing different calculations performed in the random-phase approximation and ring approximation frameworks. The importance of the exchange terms in this energy region is investigated and the changes in the nuclear responses due to the modification of the interaction are evaluated. The cal...

One-Electron Relativistic Molecules with Coulomb Interaction

As an approximation to a relativistic one-electron molecule, K we study the operator H = ( A + m Z ) l / E e 2 ~ Z j [ x R j 1 1 with Z ~ 0 , j = l e -z = t37.04. H is bounded below if and only if eZZj < 2/~z, all j. Assuming this condition, the system is unstable when e22Zj> 2/7c in the sense that E o =inf s p e c ( H ) ~ ~ as the R j~0 , all j. We prove that the nuclear Coulomb repulsion more...

Electron interaction with deoxyribose analogue molecules in gaseous phase

We present recent results on elastic and inelastic low/medium energy electron interaction with tetrahydrofuran, C4H8O, tetrahydrofurfuryl alcohol, C5H10O2 and 3hydroxytetrahydrofuran, C4H8O2 molecules in gaseous phase. A comparative study of both absolute differential cross sections for elastic electron scattering and electron energy loss spectra, in a wide incident electron energy range from 5...
