| Popis: | We have performed detailed particle-{gamma} and particle-{gamma}-{gamma} angular correlation measurements for two strong resonances observed in the elastic and inelastic scattering of {sup 24}Mg+{sup 24}Mg. These data provide us with spectroscopic information relatively uncontaminated by nonresonant amplitudes, and allow spin assignments of {ital J}{sup {pi}}=36{sup +} for two resonances at {ital E}{sub c.m.}=45.70 and 46.65 MeV. The angular correlation data for the mutual 2{sup +} inelastic scattering channel suggest a dominant decay {ital l} value of {ital l}=34 for both resonances. Correlated spin alignment data for this channel confirm our expectations for the relationship between angular momentum coupling and spin alignment for these resonances. The relatively high spin values suggest a resonance configuration in which the two {sup 24}Mg nuclei interact pole-to-pole, allowing the system to sustain a large amount of angular momentum. The pole-to-pole grazing picture is supported by the results of model calculations of the {sup 24}Mg+{sup 24}Mg{r arrow}{sup 48}Cr system. |
