Abstract
The () reaction has been performed at 26 MeV incident energy on targets of (97.5%), (97.4%), and (57%) and natural Pt. The deuterons were detected in the focal plane of the split pole magnetic spectrometer with a resolution of 16 to 20 keV full width at half maximum. In , 32 levels, 23 of which are observed for the first time, are populated below 1250 keV; in , 24 levels are observed below 1200 keV; in , due to low enrichment and target uniformity problems, only 7 levels are clearly separated. Comparison of the measured angular distributions with distorted-wave Born-approximation calculations allows parity assignments and spin limits for most of the final levels. Spectroscopic factors are deduced. A cursory investigation of the () reaction on the same targets with about 10 keV resolution has permitted us to separate several clustered low lying levels and to identify and study, using a target, a few levels of .
