Abstract
The quantum-electrodynamical fourth-order corrections for the intervals of the triplet fine structure of helium are calculated by taking into account the one-electron Lamb-shift for the self-spin-orbit coupling and the effect of the anomalous magnetic moment on the mutual spin-orbit and spin-spin coupling between two electrons. The values of the radial integrals are taken from the author's previous calculation. The calculated values of the corrections are within the range of experimental errors in the case of optical measurements but they amount to observable quantities in a microwave experiment.Keywords
