The signature of the solar axion is an increase in the rate of the X rays detected in a magnetic helioscope when the sun is within its acceptance.\n  From the absence of such a signal we set a 95% confidence level limit on the axion coupling to two photons $g_{a\\gamma\\gamma}\\equiv 1/M < 6.0\\times 10^{-10}$ GeV$^{-1}$, provided the axion mass $m_a<0.03$ eV. The limit on the coupling is factor 4.5 more stringent than the recent experimental result. ","authors_text":"(2) KEK), Akira Yamamoto (2) ((1) Univ.
