Microscopic theory of pygmy- and giant resonances:Accounting for complex 1p1h\otimes phonon and two-phonon configurations

Sergei Kamerdzhiev, Michael Shitov, Dimitri Voitenkov

The self-consistent Theory of Finite Fermi Systems (TFFS) is consistently generalized for the case of accounting for phonon coupling (PC) effects in the energy region of pygmy- and…
