Rotational Damping And Compound Formation In Warm Rotating Nuclei

摘要

The rotational damping width Γrot and the compound damping width Γcomp are two fundamental quantities that characterize rapidly rotating compound nuclei having finite thermal excitation energy. A two-component structure in the strength function of consecutive E2 transitions reflects the two widths, and it causes characteristic features in the double and triple gamma-ray spectra. We discuss a new method to extract experimentally values of Γrot and Γcomp. The first preliminary result of this method is presented.
