摘要：

The paper suggests using Bragg scattering to search for solar axions or other bosons. The enhancement factor from constructive interference can be as large as approximately 10(4) over the whole solar axion spectrum. The angular correlation of the axion-to-photon cross section can be utilized to focus the converted celestial axions by using a large surface antenna covered with a thin film (approximately mum) of single crystals. A few cases are discussed, and the potential importance of this interaction-mode in other crystalline radiation detectors is mentioned. Alternatively, existing experimental data with semiconductor or other thermal (cryogenic) detectors - not only in dark matter research - should be reevaluated. Experiments based on this proposal could measure a coupling constant at the level g(agammagamma) = 10(-8) GeV-1 or lower for an axion mass up to a few keV.
