| Abstract: | The electric multipole isovector (τ = 1) giant resonances for Δτz = 0, ± 1 are studied using the self-consistent HF-RPA theory.The distributions of strength, energies, the isospin compositions and other properties of the J = 0+, 1?, 2+ resonances in the 48Ca, 90Zr, 120Sn and 208Pb regions are calculated. Sum rules for the charge-exchange Δτz = ±1 excitations are derived. |
