Population of dipole states via isoscalar probes: the splitting of pygmy dipole resonance in ${}^{124}$Sn}

Edoardo G. Lanza, Andrea Vitturi, Elena Litvinova +1

Inelastic $\alpha$-scattering excitation cross sections are calculated for electric dipole excitations in ${}^{124}$Sn based on the transition densities obtained from the relativistic qua…
