Аннотация:According to Einstein–Maxwell-dilaton theory,the dilaton field ψ can be produced by electromagnetic fieldswith non-zero Maxwell invariant. So electromagnetic wavepropagating in an external electromagnetic field is a typicalsource of dilaton radiation. For study dilaton photoproduction in astrophysical conditions it’s interesting to considerplane elliptically polarized electromagnetic wave propagating in the electromagnetic field of magnetic dipole m ofpulsars and magnetars. The dilation field equation is solvedin case |ψ| 1. The angular distribution dilaton radiationis studied in every point of space. It’s shown that spectralcomposition of dilatons is similar to spectral compositionof plane electromagnetic wave. Amount of dilaton energyradiated in time and all directions is greatest in condition(B_1^ − B_2^2)(m_x^2 − m_y^2) ≥ 0, where B_1 and B_2 are electromagnetic wave amplitudes along the axes of polarization ellipse.This condition is valid for many neutron star systems
