A new local density functional approach for the calculation of correlation energies of many-electron atomic systems is proposed by using the exact results for the correlation energy of a two-electron system bound by a harmonic oscillator external potential. This is motivated by the fact that the cor

Decomposition of an arbitrary cartesian tensor expressed in its principal axis system into two axially symmetric cartesian tensors greatly facilitates the calculation of spectral densities, the latter being the Fourier transform of correlation functions involving ( ) elements of those tensors.

## Abstract The ethylene polymerization enthalpy, calculated through quantum‐mechanical ab‐initio methods on model systems of homogeneous Ziegler‐Natta cationic catalysts, is reported to be from two to three times greater than the experimental value of 22,3 kcal/mol. In this paper we analyze the or
