Abstract

The intermediate structures in [Formula Presented] inelastic scattering were investigated at energies around [Formula Presented] in the [Formula Presented] single excitation and the [Formula Presented] mutual excitation channels and at [Formula Presented] in the [Formula Presented] single excitation channel. The angular distributions of the magnetic substate cross sections for the [Formula Presented] (4.439 MeV) state of [Formula Presented] were measured by using the γ-ray recoil method in the center-of-mass ejectile-axis frame. It is shown that the structures at [Formula Presented] and 31.8 MeV in the [Formula Presented] channel are interpreted as resonances of [Formula Presented] or [Formula Presented] which decay dominantly through the aligned configurations with [Formula Presented] On the other hand, the structure at [Formula Presented] is accounted for by assuming the overlap of two resonances having spins and parities of [Formula Presented] and [Formula Presented] In the [Formula Presented] channel, little oscillatory structures are observed in the m-substate angular distributions so that the resonance spins cannot be extracted.
