Subsequently, Lyuboshitz [141] showed that the Ternov–Bagrov–Khapaev<br />

result could be simply and intuitively understood as a radiation reaction<br />

spin-flip due to the spontaneous emission of magnetic dipole radiation; but<br />

also noted that a generalisation of his heuristic argument to the case of<br />

charged particles was not trivial. Jackson’s comprehensive review [114] examined<br />

the Lyuboshitz argument in detail, and explained most clearly why<br />

it is essentially completely correct for neutral particles, and almost—but not<br />

quite—correct for charged particles.<br />

Clearly, a phenomenon that is so manifestly an effect of the reaction<br />

of radiation is a suitable test for the author’s results. The fact that the<br />

quantum analysis involves spontaneous radiation warns us that the classical<br />

analysis will not be complete; but nevertheless we would, following<br />

Schwinger [185, 186], expect the dimensional quantities appearing in the results<br />

to be completely classical; the spontaneity of the radiation—essentially<br />

arising through the use of discrete integers rather than continuous reals for<br />

the electromagnetic field—yielding important but dimensionless corrections.<br />

In Section 6.10.1, we briefly review the Sokolov–Ternov effect, followed by<br />

the Ternov–Bagrov–Khapaev effect in Section 6.10.2. Lyuboshitz’s elementary<br />

explanation of the Ternov–Bagrov–Khapaev effect in terms of spin-flip<br />

due to spontaneous radiation is presented in Section 6.10.3, and Jackson’s<br />

comments on both this and the Sokolov–Ternov effect are reviewed in Section<br />

6.10.4. Then, in Section 6.10.5, we consider the question from the point<br />

of view of the equations of the previous section, and compare the results with<br />

those of Lyuboshitz and Jackson.<br />

6.10.1 The Sokolov–Ternov effect<br />

In a six-paragraph note to JETP in 1961 [210], Ternov, Loskutov and Korovina<br />

(with acknowledgments to Sokolov) noted that, due to the fact that a<br />

Dirac electron moving perpendicular to a uniform magnetic field emits “syn-<br />
