Resonant structures in the {sup 20}Ne+{sup 16}O system
- Department of Physics and Astronomy, University of Pennsylvania, Philadelphia, Pennsylvania 19104 (United States)
In a search for high spin molecular states in {sup 36}Ar, the {sup 20}Ne+{sup 16}O system was studied using a differentially pumped windowless {sup 20}Ne gas target. Angle-averaged excitation functions for the {sup 20}Ne+{sup 16}O and {sup 24}Mg+{sup 12}C mass partitions were obtained for the energy range 16.39 MeV {le}{ital E}{sub c.m.}{le} 41.67 MeV in 278 keV steps. Inelastic scattering involving the {sup 16}O(0{sub 2}{sup +}, 6.05 MeV) state was separated from the nearby {sup 16}O(3{sub 1}{sup {minus}}, 6.13 MeV) state by detecting the {ital e}{sup {minus}} and {ital e}{sup +} emitted from the internal pair decay of the {sup 16}O(0{sub 2}{sup +}) state. A statistical fluctuation analysis indicates that several correlated structures are present in the current system. Tentative spin assignments based on angular distribution measurements suggest the resonant structures could be associated with rotational states of {sup 36}Ar. The results are compared with a cranked cluster model calculation. {copyright} {ital 1996 The American Physical Society.}
