In present work, we study how far the contribution of valence electrons to the HMCs of the electron–positron (e–p) momentum density can be neglected. Calculations are performed for gold within both the independent particles model (IPM) and including the e–p correlation effects non-locally, ...
c) a lone pair, a single bond, a double bond, a triple bond and a single electron - each of these is counted as a single electron group. d) bond angles may depart from the idealized angles because lone pairs of electrons take up less space than bond pairs. ...

It is found that reasonable agreement with four-electron calculations of the dipole moment is obtained when the valence orbitals are made orthogonal to the orbitals of the neglected lithium inner shell 1s electrons and that an approximate variational theorem for the energy is then valid. On the ...

A weak signature of the electronic dynamics can also be observed outside the green circle ofFig. 2a, that is, in the region dominated by the electrons that have scattered backwards from the parent ion. We note that the noise along the central vertical line is an artifact of the inversion ...
