,On a Green’s Function Method for the Calculation of Ionization Spectra in the Outer and Inner Valen structure of the spectra - such a method is the two-particle-hole Tamm-Dancoff Green’s function approximation (2ph-TDA), whereas in the outer valence region high accuracy is required. This is supplied by an extended 2ph-TDA method (e-2ph-TDA) or a method especially adapted to this energy range, the outer valence Green’s function or OVGF method.

Diagrammatic Many-Body Perturbation Theory,ation theory are both accurate and efficient. The importance of Wigner’s (2n+1) rule is noted. The impact of parallel processing computers on pertur- bative calculations is assessed. An outline of some current research on the application of diagrammatic perturbation theory to the correlation problem in atoms and molecules is presented.

The Direct CI Method,me approximate methods are also described. These methods include the internally and externally contracted CI methods. The externally contracted CI method is shown to correspond to the work of one half of an ordinary CI iteration in the large basis set limit where the overhead is negligible.

In general, the highest concentrations of melatonin were obtained in table grapes and cherries - Amar de Maxut. Among the analyzed species, table grapes presented the highest antioxid
