在兰州重离子研究装置的分离扇形回旋加速器上,用堆箔活化技术测量了100 MeV以下Mo(p,x)Tc,Mo,Nb和Zr核反应的实验截面。这些核素的截面填补了75-100 MeV能区的差距。此外,我们的实验结果与以前发表的值取自EXFOR数据库和理论计算预测的TAPIS-1.95程序与六个能级密度模型,这是重要的输入参数影响的激发函数进行了比较。在结果方面,我们的测量显示出良好的协议与理论计算的大多数放射性核素。能级密度模型在激发函数的描述上仍需进一步优化。
Experimental cross-sections for the nuclear reactionsMo(p,x)Tc,Mo,Nb andZr were measured up to 100 MeV, carring out at separated sector cyclotron of the Heavy Ion Research Facility in Lanzhou, using the stacked-foil activation technique. The cross-sections of these nuclides in this work fill the gap in 75–100 MeV energy range. In addition, our experimental results were compared with the previously published values taken from EXFOR database and the theoretical calculations predicted by TALYS-1.95 code with six level density models, which are important input parameters affecting the excitation functions. In terms of results, our measurements show good agreement with the theoretical calculations for most of the radionuclides. Level density models still needs to be further optimized in the description of excitation functions.
