Abstract: We calculate the total cross section for the production of photons from thescattering of axions by a strong inhomogeneous magnetic field in the form of a2D delta-function, a cylindrical step function and a 2D Gaussian distribution,which can be approximately produced by a solenoidal current. The theoreticalresult is used to estimate the axion-photon conversion probability which couldbe expected in a reasonable experimental situation. The calculated conversionprobabilities for QCD inspired axions are bigger by a factor of 2.67 for thecylindrical step function case than those derived by applying the celebrated1D calculation of the inverse coherent Primakoff effect. We also considerscattering at a resonance \$E {axion} \sim m {axion}\$, which corresponds to thescattering from a delta-function and gives the most enhanced results. Finally,we analyze the results of this work in the astrophysical extension to suggest away in which they may be directed to a solution to some basic solar physicsproblems and, in particular, the coronal heating problem.
