Largely Deformed Dinuclear System Formed in 19F+27Al Dissipative Collision

Abstract

Excitation functions are measured for different charge products of the19F+27Al reaction in the laboratory energy range110.25–118.75 MeV in steps of 250 keV at θlab = 57°,31° and −29°. The coherence rotation angular velocities ofthe intermediate dinuclear systems formed in the reaction are extractedfrom the cross section energy autocorrelation functions. Compared theangular velocity extracted from the experimental data with the onesdeduced from the sticking limit, it is indicated that a largerdeformation of the intermediate dinuclear system exists.
