Basic Equations of the Quasiparticle-Phonon Nuclear Model with the Effects Due to the Pauli Principle and the Phonon Ground State Correlations

摘要

A system of basic equations of the quasiparticle-phonon model is obtained for energies and a structure of excited states described by the wave functions containing one- and two-phonon components. The effects due to the Pauli principle for two-phonon components and the phonon ground state correlations of a spherical nucleus are taken here into account. The quantitative estimations of these effects are given by a simplified scheme. The relation between these equations with the results from other theoretical approaches is discussed.
