TOTAL CROSS-SECTION FOR PHOTON AXION CONVERSIONS IN EXTERNAL ELECTROMAGNETIC FIELD

D. V. SOA, H. N. LONG and T. D. THAM

We reconsider the conversion of the photon into axion in the external electromagnetic fields, namely in the static fields and in a periodic field of the wave guide. The total cross-sections for the conversion are evaluated in detail. The result shows that with strong strength of external electromagnetic fields, the cross-sections are large enough to measure the axion production. In the wave guide, there exists the resonant conversion at the low energies, in which the value of cross-sections is much enhanced.
