Magnetic-field-dependent angular distributions and linear
... M = ±1 sublevels, when the photon’s polarization is neglected. The B dependence of the angular distributions of Aif results from the fact that the MIT transition rate is proportional to B 2 [4]. As an example, we show the angular distributions of the rates in Fig. 1 for the transitions in Ne-like Mg ...
