| Abstract;A coincidence Doppler spectroscopy was applied to polymer, using two Ge solid state detectors (SSD). The ratio of peak to back ground of the Doppler broadening spectrum obtained by one SSD detector was about 10-3.This ratio was improved by taking coincidence of two Ge detectors, resulting in the order of 10-5. By this method positron annihilation with inner orbital electrons with large momentum can be detected. This can be applied to microanalysis of metallic elements with a high momentum inner orbital electrons. (author abst.) |
