Abstract

Recent measurements of the most probable kinetic energy release in fission are compared in order to study the dependence on nuclear species. Appropriate corrections to data obtained with semi-conductor detectors, particularly with regard to calibration procedures, are discussed and applied. Corrected results are listed in Table I and plotted in Fig. 1. It is found that the most probable kinetic energy release in fission can be simply expressed by the function. $< E_{k} > = 0.1071 Z^{2} / A^{1 / 3} + 22.2 MeV .$

The corrected <E_k> values are compared with recent liquid drop calculations and good agreement is found for Z²/A less than 35, but not above this value. Effects of mass asymmetry are also briefly discussed. Analysis of the data indicates that the most probable kinetic energy release is essentially independent of excitation energy. Use was made only of results published since 1961. Prior data can be found in the review of Huizenga and Vandenbosch.

裂变碎片动能数据的关联

为了研究裂变中最可能的动能释放对核种类的依赖性，本文比较了最近的测量结果。讨论并应用了对半导体探测器获得的数据的适当修正，特别是关于校准程序的修正。修正后的结果列于表1，并绘制在图1中。发现裂变过程中最可能的动能释放可以用函数简单表示。& lt; Ek> = 0.1071 z2 / A1/3 + 22.2兆电子伏。修正后的<Ek>将Z2/A值与最近的液滴计算值进行比较，发现Z2/A小于35，但不高于此值，结果很一致。本文还简要讨论了质量不对称的影响。对数据的分析表明，最可能的动能释放基本上与激发能无关。只使用1961年以来发表的结果。先前的数据可以在Huizenga和Vandenbosch的综述中找到。
