Abstract:
Systematic nuclear resonance fluorescence experiments, including model independent parity determinations, provided evidence for enhanced E1 excitations near 2.5 MeV excitation energy in the deformed nuclei 150Nd, Gd-160, and Dy-162, Dy-164. The corresponding J(pi) = 1- states are interpreted as two-phonon excitations due to the coupling of octupole (J = 3-, K = 1) and quadrupole gamma vibrations (J = 2+, K = 2). The results can be explained in the framework of the sdf interacting-boson-approximation model and the dynamic collective model describing octupole vibrations and their coupling to quadrupole vibrations in deformed nuclei.
