Dipole and spin-dipole strength distributions in $$^{124,126,128,130}\mathrm {Te}$$ 124 , 126 , 128 , 130 Te isotopes

Abstract

We try to present the structure of \(1^{-}\) excitations in open-shell \(^{124,126,128,130}\mathrm {Te}\) isotopes. Electric dipole states are investigated within a translational and Galilean invariant model. Also, a theoretical description of charge-conserving spin-dipole \({1}^{-}\) excitations is presented for the same isotopes. The energy spectra for both kinds of excitations are analysed in detail. Furthermore, a comparison of the calculated cross-sections and energies with the available experimental data is given.
