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

Excitation functions are measured for different charge products of the ^19F＋^27AI 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.

1. IntroductionLet (M, g) be a four dimensional Riemannian manifold and let P be a principal bundlewith compact Lie structure group G over M. The Yang-Mills functional is defined bywhere F denotes the curvature of a connection D and dM is the volume form induced bythe metric g on M. All integrals on M in this paper will be with the volume form dM, sowe will not write it explicitly.Donaldsonl3] and K. Uhlenbeck[18'19] obtained many important results about Yang-Millsequations (see also […
