Abstract
We calculate the two-photon exchange correction to the Lamb shift in muonic He-3 ions within the dispersion relations framework. Part of the effort entailed making analytic fits to the electron-He-3 quasielastic scattering data set, for purposes of doing the dispersion integrals. Our result is that the energy of the 2S state is shifted downwards by two-photon exchange effects by 15.14(49) meV,
