✦ Synopsis
The electron density difference between the correlated density of N2 and the superimposed AHF atom densities is calculated using the PERTCI program system and various AHF GTO wavefunctions. The result is compared with the corresponding experimental density recently derived from electron diffraction measurements in the gas phase.

Scaling a one-electron density for M electrons to the correct normalization for N electrons is known to give an N-representable density. Here we show that a similar scaling for the electron pair distribution is generally not N-representable. The two-body r( x,x,; X:x;)
Until now, solids with strongly correlated electrons can be treated only by model Hamiltonians. Even then a calculation of spectral densities is not simple, because the strong Coulomb interactions prevent us from treating correlations perturbatively. We show that projection and partitioning techniqu
