19F+27Al耗散反应中双核系统的转动与形变
Rotation and Deformation of the Dinuclear System Formed in Dissipative Reaction of 19F+27Al
【摘要】 测量了19F+27Al耗散反应产物B,C,N,O,F和Ne的激发函数,入射束流的能量从110.25MeV 到118.75MeV,能量步长为250keV.从产物的能量自关联函数中提取了反应中所形成的中间双核系统的转动惯量,与相粘模型计算的刚体转动惯量相比较,结果表明形成的双核系统有大的形变.
【Abstract】 Excitation functions of the reaction products B, C, N, O, F and Ne emitted from the dissipative reaction of 19F+27A1 have been measured at incident energies from 110.25MeV to 118.75MeV in steps of 250keV. The moments of inertia of the intermediate dinuclear system formed in the reaction are extracted from the energy autocorrelation functions of the products. Comparing the moment of inertia extracted from the experimental data with the calculated one by using the sticking limit, it indicates that the formed dinuclear system has a large deformation in the reaction process.
