NUCLEAR STRUCTURE ^{50,52,54,56,58,60,62,64,66,68,70,72,74,76}Ca, ^{78,80,82,84,86,88,90,92,94}Ni, ^{134,136,138,140,142,144,146,148,150,152,154,156,158,160}Sn; calculated charge-exchange dipole strength distributions for neutron-rich isotopes as functions of the excitation energy, fraction of the summed strengths of the pygmy dipole resonance to the total sum of strengths. ⁵⁴Ca, ⁸⁶Ni; calculated transition densities to giant, pygmy resonances and other states, matrix element for the pygmy resonance. Fully self-consistent proton-neutron quasiparticle-random-phase approximation (pnQRPA) with the Skyrme energy density functional (EDF).
