Abstract
The excitation function of the reaction7Li(d, α)5He has been measured between 0.6 and 2.0 MeV in steps of 50 keV. The two resonances at 0.75 and 1.00 MeV corresponding to the levels at 17.28 and 17.48 of the compound nucleus9Be were resolved. Angular distribution measurements were performed at 14 different energies mainly near the 1.00 MeV resonance.
From the analysis of the data the 17.28 MeV level seems to be a positive parity state (3/2+ → 7/2+) whilst a negative parity (7/2− or 9/2−) is indicated for the 17.48 MeV level. This is contrary to the order of parities as given in the literature.
