    Abstract

    In hydrogen, an external magnetic field, which we calculate to be ?16.65?T, cancels the internal field caused by the electron motion in the magnetic sublevels with mJ=+1/2. This results in an energy-level degeneracy between states with nuclear magnetic sublevels mI of opposite signs. The evaluation of this field has been calculated previously with the use of the low-field quantum numbers F,?mF. We show that this calculation is considerably simpler in the high-field mJ,?mI representation. A comparison is given with the earlier work.
