摘要
报道了102.25-109.25MeV^(19)F+^(51)V 耗散反应激发函数的振荡现象,用统计学方法分析了截面涨落的能量相干,振荡结构表现出很强的出射道相关性.能量相干宽度Γ随出射产物的原子序数和质量数而变化.讨论了双核系统的角速度阻尼与转动能耗散之间的关系.
Excitation function fluctuations for projectile-like fragments from ^(19)F+^(51)V dissipative reaction within the energy region of 102.25—109.50MeV are reported.The statistical meth- od is applied to the analysis of energy coherence in the cross section fluctuations and the strong cross correlation between exit channels is obtained.The dependences on charge num- ber and on mass number are presented.The relation between angular velocity damping and the rotational energy dissipation is discussed.
