Search for solar axions

We have searched for a flux of axions produced in the Sun by exploiting their conversion to x rays in a static magnetic field. The signature of a solar axion flux would be an increase in the rate of x rays detected in a magnetic telescope when the Sun passes within its acceptance. From the absence of such a signal we set a 3{σ} limit on the axion coupling to two photons g_aγγ{≡}1/M3.6×{}10^-9 GeV^-1, provided the axion mass mₐ0.03 eV and 7.7×{}10^-9 GeV^-1 for 0.03 mₐ0.11 eV.
