Description

High resolution and sensitivity studies of the nuclear dipole response in 138Ba have been performed in (γ, γ') experiment. The electric dipole character of the 'pygmy' mode was experimentally verified for excitations from 4.0 to 8.5 MeV. Experimental findings have been compared with the quasiparticle phonon model. A new understanding about the character and the evolution of the pygmy resonance emerges from comparison of the experimental results with the theoretical calculations.
