Cluster perturbation theory. II. Excitation energies for a coupled cluster target state 

Pawlowski, Filip; Olsen, Jeppe; Jorgensen, Poul; 0000-0002-5928-2140 (2020-05-07)
In cluster perturbation (CP) theory, we consider a target excitation space relative to a Hartree-Fock state and partition the target excitation space into a parent excitation space and an auxiliary excitation space. The ...
