The decay pattern of the Pygmy Dipole Resonance of 140Ce
چکیده انگلیسی

The decay properties of the Pygmy Dipole Resonance (PDR) have been investigated in the semi-magic N=82N=82 nucleus 140Ce using a novel combination of nuclear resonance fluorescence and γ–γ   coincidence techniques. Branching ratios for transitions to low-lying excited states are determined in a direct and model-independent way both for individual excited states and for excitation energy intervals. Comparison of the experimental results to microscopic calculations in the quasi-particle phonon model exhibits an excellent agreement, supporting the observation that the Pygmy Dipole Resonance couples to the ground state as well as to low-lying excited states. A 10%10% mixing of the PDR and the [21+×PDR] is extracted.
