Abstract
From the general argument (see Sect. 5.1), only the Dirac neutrino can have a magnetic moment. The transition moment, which is relevant to νi → νj + γ, may exist for both Dirac and Majorana neutrinos. A straightforward calculation of the one-loop diagram [1012,1204] (see also [1490]) depicted in Fig. 8.15 gives for the Dirac neutrino,
, where q = p′ - p, and

, with
