摘要
本文简要介绍了一种用于奇异核延迟粒子衰变产生的低能α粒子探测与鉴别的望远镜系统。该望远镜由气体电离室（△Ｅ）和Ｓｉ（Ａｕ）面垒型探测器（Ｅ）构成。由于在奇异核延迟粒子衰变中通常产生特征低能α粒子和质子，因此探测并鉴别这些粒子已成为研究新的核衰变机制和发现新核素的必要手段。望远镜已用于Ｐ＋２０Ｎｅ反应中探测低能α粒子，得到了很好的△Ｅ－Ｅ双维谱。
A △E E telescope which can detect and idenlify the low energy particles in unusual nuclei delay decay is described. The telescope consists of ionization chamber (△E) and Si(Au) surface barrier detector.Because of low energy α particle and protons are usually produced in unusual nuclei delay decay, so detection of these particles become necessary for research of new nuclear decay mechanism and discovery of new nuclei. This telescope has been used in P+ 20 Ne reaction and has identified a 0.695 MeV α particle. (
