| 摘 要： | 文章计算了喷氦传输、转盘收集和粒子望远镜探测系统的探测效率,并编制成计算机程序,以实验数据和模拟参数输入迭代计算,可得核的实验反应截面、半衰期和粒子发射分支比等参数,其计算结果在合理范围内与理论预言符合一致。此计算特别适用于远离β稳定线短寿命核素的探索研究。

| Abstract: | The detection efficiency of helium-jet system with rotating disc and particletelescope is calculated. With inputing experimental data and analogue parametersthe experimental cross-section, half-life and particle branching ratio as well asother parameters can be obtained. The results agree reasonably with theoreticpredictions. The calculation is suitable particularly for searching nuclides withshort life far from beta stability. |
