✦ Synopsis

The damping of collective rotational motion is studied microscopically, making use of shell model calculations based on the cranked Nilsson deformed mean-field and on residual two-body interactions, and focusing on the shape of the gamma-gamma correlation spectra. and on its systematic behavior. It is shown that the spectral shape is directly related to the damping width of collective rotation, F~o~, and to the sl)reading width of manvparticle many-hole configurations, F,. The rotational damping width is affected bv tile shell structure, and is very sensitive to the position of 11., Yerlni surface, besides mass mmd)er, spin and deformation. This produces a ricll 'hriol ' of features in Llle rol.aliona.I damping phenomena.
