Abstract
A study of the Be( He, He) Be reaction has been performed at Be beam energies of 25.0, 27.0, 29.0, 32.0, 34.0, 38.0, 40.0, 42.0, 44.0 and 46.0 MeV. The measurements were to explore possible molecular rotational bands in C. Three states at excitation energies of E 18.8, 19.76 and 20.66 MeV have been measured and their spins have been determined to be 5 , 5 and 6 , respectively. © Published under licence by IOP Publishing Ltd.
