An external magnetic field is applied to the classical hydrogen atom treated in classical electromagnetic theory including classical electromagnetic zero-point radiation. In an earlier article, it was shown that the average value of each of the electron's action variables appears as a discrete value, corresponding to a representation of the rotation group, because of resonance between the periodic orbit of the electron and the random classical zero-point radiation. Here it is shown that, in the presence of a magnetic field and because of resonance, the classical orbital motion of the electron is in resonance with random classical zero-point radiation only for orientations of the orbit which take integer values for the angle made with the direction of the magnetic field, but excluding the m=0 orientation where the magnetic field is parallel to the orbital plane of the electron. Classical electromagnetic explanations are given for the Stern-Gerlach result, and for the Zeeman effect.

Abstract The linewidth of the Hanle effect signal of the orientation and alignment of the resonance level 5 1P1 of the cadmium isotop Cd114 is measured as a function of the pressure of various noble gases, of hydrogen and deuterium. The cross sections for broadening of the orientation and alignment signals due to atomic collisions are derived from the pressure dependence of the linewidth. The multipole depolarization-cross sections were found to be In order to separate the depolarization effects from quenching effects in the case of hydrogen and deuterium polarization measurements of the resonance radiation were also undertaken. The alignment depolarization- and the quenching cross sections were found to
