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。
In this paper, a telescope system for detection and discrimination of low energy α particles generated by the delayed nuclear decay of singular nuclei is briefly introduced. The telescope consists of a gas ionization chamber (ΔE) and a Si (Au) surface-type detector (E). Due to the regular generation of low-energy alpha particles and protons in the degenerated particles, the detection and identification of these particles have become the necessary means to study new nuclear decay mechanisms and discover new nuclides. Telescopes have been used to detect low-energy alpha particles in the P + 20Ne reaction, resulting in a good ΔE-E two-dimensional spectrum.
