摘要:

用叠箔辐照和γ能谱实验方法,将镝原子上质子诱发核反应的长寿命产物的活化截面数据扩展到65 MeV。在36-65 MeV能量范围内,报告了放射性核素$^{159}$ Dy、$^{157}$ Dy、$^{155}$ Dy、$^{161}$ Tb、$^{160}$ Tb、$^{156}$ Tb、$^{155}$ Tb、$^{154m2}$ Tb、$^{154m1}$ Tb、$^{154g}$ Tb、$^{153}$ Tb、$^{152}$ Tb和$^{151}$ Tb形成的实验截面数据,并与1964年的旧数据集进行了比较。实验数据还与最新在线库TENDL 2013中列出的ALICE和EMPIRE核模型代码以及TADIS核反应模型代码的截面计算结果进行了比较。

英文摘要:

Activation cross-sections data of longer-lived products of proton induced nuclear reactions on dysprosium were extended up to 65 MeV by using stacked foil irradiation and gamma spectrometry experimental methods. Experimental cross-sections data for the formation of the radionuclides $^{159}$Dy, $^{157}$Dy, $^{155}$Dy, $^{161}$Tb, $^{160}$Tb, $^{156}$Tb, $^{155}$Tb, $^{154m2}$Tb, $^{154m1}$Tb, $^{154g}$Tb, $^{153}$Tb, $^{152}$Tb and $^{151}$Tb are reported in the 36-65 MeV energy range, and compared with an old dataset from 1964. The experimental data were also compared with the results of cross section calculations of the ALICE and EMPIRE nuclear model codes and of the TALYS nuclear reaction model code as listed in the latest on-line libraries TENDL 2013.
