α-Clusters in ^16O
Abstract
There has been previous experimental evidence of an interesting four α linear configuration in ^16O [1]. At the Notre Dame FN Tandem Accelerator we explored the reaction of ^ 12C+α->^16O->^8Be+^8 Be. An array of Si strip detectors was set up at the forward angles to observe the final individual four α- particles [2]. Afterwards, from the ^8Be+^8Be channel, an excitation curve was constructed for an energy range of 12- 20 Mev. In addition a ^12C (,) transfer reaction was carried out to study the same α-cluster structure in ^16O, which required additional neutron detectors placed at the backward angles. Interesting α-cluster levels detected in the two reactions will be analyzed in detail (such as the angular distribution). The preliminary results on the existence of the linear α structure will be presented.[4pt] [1] P. Chevallier et al., Phys. Rev. 160, 827 (1967).[0pt] [2] P.J. Haigh et al., J. Phys. G: Nucl. Part.
