The Compton conversion of axions to photons, A + e -> e + gamma; the axioelectric effect, A + e + Z -> e + Z; the decay of axions into two photons, A -> 2 gamma; and inverse Primakoff conversion on nuclei, A + Z -> gamma + Z, are considered. Model-independent limits on axion-electron (g(Ae)), axion-photon (g(A gamma)), and isovector axion-nucleon (g(3AN)) couplings are obtained: vertical bar g(Ae) x g(3AN)vertical bar <= 5.5 x 10(-13) and vertical bar g(A gamma) x g(3AN)vertical bar <= 4.6 x 10(-11) GeV-1 at m(A) < 1 MeV (90% confidence level). These limits are 2-4 orders of magnitude stronger than those obtained in previous laboratory-based experiments using nuclear reactors and accelerators. |
