标题： Signatures of Statistical Decay

摘要： 衰变能量在反应产物的动能和它们的形成Q值之间的分配可以通过适用于高度激发核的统计推导获得，并且表明它们处于恒定比例。 我们在35A MeV的Cl + C反应中形成的定义明确的系统内，测量了激发能范围广泛的动能分数 $R = \Sigma E_{kin}/(\Sigma E_{kin} + \Sigma Q_0)$。 本工作以及最近由其他几个小组进行的实验中观察到的激发能、带电粒子多重性和中间质量碎片多重性之间的关系，可以从平均动能和Q值的推导中得出。 显示英文摘要

摘要： The partition of decay energy between the kinetic energy of reaction products and their Q-value of formation is obtained in a statistical derivation appropriate to highly excited nuclei, and is shown to be in a constant ratio. We measure the kinetic energy fraction, $R = \Sigma E_{kin}/(\Sigma E_{kin} + \Sigma Q_0)$, over a wide range of excitation energy for well-defined systems formed in the Cl + C reaction at 35A MeV. Relationships between excitation energy, charged-particle multiplicity, and intermediate-mass-fragment multiplicity, observed in this work and in recent experiments by a number of other groups, follow from the derivation of the average kinetic energies and Q-values.
