Abstract:
Parity quantum numbers for dipole-excited
states of the nuclei 92Zr and 96Mo have been
determined from azimuthal asymmetries of
nuclear resonance fluorescence intensities
induced with the linearly polarized photon
beam of the HIGS facility at Duke University.
This parity information is crucial for an
interpretation of the investigated J = 1
states as two-phonon excitations originating
from inhomogeneous phonon coupling.
