摘要

Tamm-Dancoff and random-phase approximations are formulated in the canonical Hartree-Fock-Bogoliubov quasi-particle basis and adopted to compute the E1 response in Ca isotopes using an intrinsic Hamiltonian composed of a V_(lowk) potential, deduced from the CD-Bonn nucleon-nucleon interaction, corrected with phenomenological density dependent and spin-orbit terms. Attention is focused on the evolution of the dipole strength distribution, including the low-lying transitions associated to the pygmy resonance, in going from the N = Z ~(40)Ca to Ca isotopes with neutron excess.
