论文摘要
反应中高自旋和低自旋异构体产量的调查结果的结果$^{134} $ ba（$α$，n）$^{137} $ ce在α粒子的能量范围内15 $÷$ 31 MEV基于同类对成员的诱导活动的外观测量。确认了这些反应中第一个反应的异构体横截面比的异常行为。获得了第二和第三的独特的同构横截面比。揭示了第四个反应的特征，它在基本研究中的应用是有希望的。分析了通过流行的计算机代码对这种动态描述的质量。
Results of the investigations of the yield of high-spin and low-spin isomers in reactions $^{41}$K($α$,n)$^{44}$Sc, $^{86}$Sr ($α$,n)$^{89}$Zr, $^{112}$Sn($α$,n)$^{115}$Te, and $^{134}$Ba($α$,n)$^{137}$Ce in the energy range of the alpha particles 15 $÷$ 31 MeV based on off-beam measurements of induced activity of members of the isomeric pair are presented. The anomalous behavior of the isomeric cross-section ratios for the first of these reactions is confirmed. Uniquely large isomeric cross-section ratios for the second and third ones are obtained. The features of the fourth reaction, which are promising for its application in fundamental research, are revealed. Quality of the description of this dynamics by popular computer codes is analyzed.
