Recent results from the excitation of dipole states at the HlγS facility

Conference Paper

High-sensitivity studies of El and Ml excitations observed in the 138Ba(γ,γ') reaction at energies below the neutron emission threshold have been performed. The electric dipole character of the so-called "pygmy" mode was experimentally verified for excitations from 4.0 -8.6 MeV. The fine structure of the Ml "spin-flip" mode was observed for the first time in N = 82 nuclei. © 2009 American Institute of Physics.
