Abstract Excitation functions are measured for different charge products of the 19F+27Al reaction in the laboratory energy range 110.25--118.75MeV in steps of 250keV at θlab=57°, 31° and -29°. The coherence rotation angular velocities of the intermediate dinuclear systems formed in the reaction are extracted from the cross section energy autocorrelation functions. Compared the angular velocity extracted from the experimental data with the ones deduced from the sticking limit, it is indicated that a larger deformation of the intermediate dinuclear system exists.
