Abstract

A new technique has been used to seek solar axions with a single-crystal germanium detector. It exploits the coherent conversion of axions into photons when their angle of incidence satisfies the Bragg condition with a crystalline plane. The analysis of approximately 1.94 kg yr of data from the 1-kg DEMOS detector in Sierra Grande, Argentina, yields a new laboratory bound on the axion-photon coupling constant (gαγγ < 2.7 × 10-9 GeV-1), irrespective of the axion mass up to ∼1 keV.
