同位素产量的指数标度的研究在很宽的范围内的激发能和冻结出体积的不同大小的源，在初级和渐近阶段的衰变的框架中的微正则多重碎裂模型。有人发现，缩放参数有很强的依赖于所考虑的对平衡源和激发能量，并受到二次粒子发射的破碎碎片。没有显着的影响，所考虑的同位素比的冻出体积已被观察到。微正则结果从巨正则期望的偏差进行了讨论。
The exponential scaling of isotopic yields is investigated for sources of different sizes over a broad range of excitation energies and freeze-out volumes, in both primary and asymptotic stages of the decay in the framework of a microcanonical multifragmentation model. It was found that the scaling parameters have a strong dependence on the considered pair of equilibrated sources and excitation energy and are affected by the secondary particle emission of the break-up fragments. No significant influence of the freeze-out volume on the considered isotopic ratios has been observed. Deviations of microcanonical results from grandcanonical expectations are discussed.
