Precise numerical calculation of radiofrequency intervals between hyperfine sublevels of the (37,35) state of the antiprotonic helium-4 atom is presented. Theoretical consideration includes the QED corrections of order m{alpha}{sup 6} to the electron spin-orbit interaction. Only the leading order contribution in the electron-to-antiproton and electron-to-{alpha} particle mass ratios is considered, so the {alpha} particle and antiproton are treated nonrelativistically. The effective Hamiltonian is derived using the formalism of the nonrelativistic quantum electrodynamics.
