Abstract

Excitation functions were measured for states of 21Ne populated by the 12C(13C, α) reaction over the bombarding energy range Elab = 18.2–32.0 MeV (18.4–27.0 MeV) at θlab = 7°(25°) in in 200 keV steps, and average coherence widths of states and the moment of inertia of the compound nucleus 25Mg were obtained from these excitation functions. A statistical analysis of these data was performed. Angular distributions for states in 21Ne to 10 MeV in excitation energy were measured at θlab = 7°, 18°, 28° and 43° at bombarding energies from 29.0 to 31.0 MeV in 400 keV steps. These data along with Hauser-Feshbach predictions allow us to suggest spins for some states as well as to suggest possible candidates for rotational bands in 21Ne.
