47. This Comment estimates the low-energy contribution to the g factor of the 2P states of hydrogen to be δgL(2P)=-0.24α3. In order to convert this value to the gJ factor addressed in the present investigation, it should be multiplied by [j(j+1)+l(l+1)-s(s+1)]/[2j(j+1)]. In units of the coefficient b20 defined by Eq. (66), this estimate corresponds to δb20(2P1/2)=-4.0 and δb20(2P3/2)=-2.0, in strong disagreement with our numerical results.
