Abstract

The linearly polarized γ-ray beam produced by the [Formula Presented] facility has been used to determine the parity of two previously known dipole excitations in [Formula Presented] The azimuthal asymmetry of γ rays produced in the process of nuclear resonance fluorescence indicated that the dipole state at 4.742 MeV, recently discussed as a new form of [Formula Presented] excitation, is in fact a [Formula Presented] state. The [Formula Presented] state at 4.742 MeV must, therefore, be reconsidered as the [Formula Presented] member of the quadrupole-octupole coupled two-phonon multiplet. A second state at 7.535 MeV was also assigned [Formula Presented].
