NUCLEAR STRUCTURE ^{16,18,20,22,24,26}O, ^{40,42,44,46,48,50,52,54,56,58,60,62}Ca, ³⁰Ne, ³²Mg, ³⁴Si, ³⁶S, ³⁸Ar, ⁴⁰Ca, ⁴²Ti, ⁴⁴Cr, ⁴⁶Fe; calculated energies of 1-, 2+ and 3- levels, B(E2) for the first 2+ states, B(M1) values of 1+ states, occupation probabilities for ³⁶S, ³⁸Ar, ^54,56Ca, energies and B(E1) of first three 1- states in ¹⁸O. ²⁰O, ⁵⁰Ca; calculated B(E1) and transition densities for the states identified as pygmy dipole resonances (PDR). Hartree-Fock, Bardeen, Cooper, and Schrieffer, and quasiparticle random-phase-approximation (HF+BCS+QRPA and QRPA(F)) calculations with finite-range interaction of Gogny type . Comparison with experimental data.
