Abstract
Results are reported of an experimental search for the unique, rapidly vary ing temporal pattern of solar axions coherently converting into photons via the Primakoff effect in a single crystal germanium detector when axions ar e 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, yie lds 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.
