摘要：

The use of a multisegment annular Si detector together with a multiline electronic processing system has led to an improvement of the detection limit in Rutherford backscattering spectrometry by about two orders of magnitude as compared to the standard single-line arrangement. With regard to nuclear reaction analysis, using particle/γ-ray resonance processes, similar large enhancements have been realized by an effective background-suppression system eliminating environmental and cosmic radiation. The present state of both experimental facilities will be demonstrated and compared with other trace-element detection techniques. © 1990.
