摘要：

Results are reported of an experimental search for the unique, rapidly varying temporal pattern of solar axions coherently converting into photons via the Primakoff effect in a single crystal germanium detector when axions are incident at a Bragg angle with a crystalline plane. The analysis of 1.94 kg yr of data from the I kg DEMOS detector in Sierra Grande, Argentina, yields a new laboratory bound by an axion-photon coupling of g(a gamma gamma) < 2.7 x 10(-9) GeV-1, independent of axion mass up to similar to 1 keV. [S0031-9007(98)07812-0].
