Description
The linearly polarized γ-ray beam produced by the HIγS facility has been used to determine the parity of two previously known dipole excitations in 88Sr. 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 M1 excitation, is in fact a 1- (E1) state. The 1- state at 4.742 MeV must, therefore, be reconsidered as the Jπ=1- member of the quadrupole-octupole coupled two-phonon multiplet. A second state at 7.535 MeV was also assigned Jπ=1-
