Abstract
Excitation functions of the projectile-like fragments in the dissipative reaction19F+51V have been measured at θ1 = 21.7°, 36.1° and 40.5°. The incident energies are from 102.25 to 109.50 MeV in 250 keV steps. The energy coherence width г and the rotation angular velocities ω of the corresponding dinuclear systems are extracted. The coherence rotation and its importance in the reaction process are discussed.
