概要

• 論文の詳細を見る

• The influence of the particle-phonon coupling on pairing correlations in finite systems is studied by solving the Dyson equation including the anomalous (pairing) Green function. We develop a formalism which allows to solve this equation with a minimum of approximations. The resulting expressions are used for the study of quasiparticles in finite nuclei. The solution of the Dyson equation is compared with the exact diagonalization of the particle-phonon coupled Hamiltonian, and a simpler treatment based on Bloch-Horowitz perturbation theory.
