Abstract
We present a theoretical consideration of the radiative twophoton finitenuclearsize contributions to the Lamb shift in a light muonic atom. They are of the order of alpha(Z alpha)(5)m and may depend differently on MRN. The contributions are due to the electronic and muonic vacuum polarization and the muon selfenergy. The consideration is done within the external field approximation. We also found the leading logarithmic finitenuclearsize contributions in the next order. One of them is of the order alpha(Z alpha)(6)ln(2)(Z alpha)(mR(N))(2)m and the other is of the order alpha(2)(Z alpha)(5)ln(2)(m(e)R(N))(mR(N))(3)m. Special attention is paid to higherorder effects in muonic hydrogen and the related applications of various parametrizations of the proton electric form factors. We also consider the general expressions in coordinate space for the finitesize radiative contributions to the Lamb shift in twobody muonic atoms. The numerical results are present for the atoms with Z <= 10.
