THE BE-8-20 MOLECULAR RESONANCES IN THE C-12+O-16 COLLISION(NE)

Excitation functions of the C-12(O-16, Be-8)Ne-20 reaction leading to some low-lying states in Ne-20 have been studied at E(c.m.) = 22 appro ximately 29 MeV. Some new resonances are identified with fluctuation a nalysis, and their spin and parity are determined. If we plot them on a E(c.m.) vs. J(J + 1) plane together with resonances reported previou sly in the same reaction channel, they seem to constitute a rotational band which coincides with the elastic band of the Be-8 + Ne-20 system rather than with that of the C-12 + O-16 system. Furthermore these re sonances are found to persist in having almost negligible correlation in energy with those identified in the C-12 + O-16 channels. A resonan ce at E(c.m.) = 26.9 MeV which has been proposed by Eswaran et al. as a superdeformed shape isomeric state is not identified in the present data.
