摘要:1,166,890. Photo-electric analysis of gammarays. OSTERREICHISCHE STUDIENGESELLSCHAFT F R ATOMENERGIE G.m.b.H. Nov. 3, 1967 [Nov.4, 19661, No.50052/67. Heading G1A. Gamma-rays are analysed by directing them on to a semi-conductor detector 1 and receiving rays back-scattered from the detector on a second semi-conductor detector 2, coincident outputs from the two detectors being amplified at 4 and 5, added together at 7 and passed to a multi-channel analyser 10 via a delay stage 8 and gate 9 operated by the coincidence circuit 6. 1,166,890.
