This paper describes a method of preparing a high resolution coaxial Ge (Li) detector by using native germanium single crystal. By performing some improvement on techniques
the best result of the coaxial Ge (Li) detector with sensitive volume 78cc has been obtained
the resolution of the divice is 2.0 keV for
