  It is assumed that axions exist and are created in the Sun by Primakoff
conversion of photons in the Coulomb fields of nuclei. Detection rates are
calculated in germanium detectors due to the coherent conversion of axions to
photons in the lattice when the incident angle fulfills the Bragg condition for
a given crystalline plane. The rates are correlated with the relative positions
of the Sun and detector, yielding a characteristic recognizable sub-diurnal
temporal pattern. A major experiment is proposed based on a large detector
array.
