Fourth-order perturbative extension of the single-double excitation coupled-cluster method, Part II: Angular reduction
Andrei Derevianko
Abstract
We tabulate angularly reduced fourth-order many-body corrections to matrix elements for univalent atoms, derived in [A. Derevianko and E.D. Emmons, Phys. Rev. A 65, 052115 (2002)]. In particular we focused on practically important diagrams complementary to those included in the coupled cluster method truncated at single and double excitations. The derivation and angular reduction of the large number of diagrams have been carried out with the help of symbolic algebra software.
