Abstract

Resonance reactions offer that vital element of simplicity required in nuclear spectroscopy, especially when they involve entrance and exit channels of channel spin 0 or 1/2, since then the formation and decay of any one of several possible intermediate states Jπ in a compound nucleus can take place only via a unique pair of incoming and outgoing partial waves 1, 1′ associated with angular distributions of highly individualistic shape and magnitude. The potentialities have already been intensively, and fruitfully, exploited [1] in studies of the 13C(α,no)16O reaction to arrive at spin and parity assignments to high-lying states of 17O occupying the region of level overlap where coherent interference between a pair of levels of unlike parity manifests itself in disruption of the 90° symmetry of the ensuing angular distribution.
