THE RADIATION OF NEUTRAL PARTICLE CARRYING MAGNETIC MOMENT

Abstract
The radiation of neutral particle that carries magnetic moment and executes non-inertial motion in the transverse magnetic field is analyzed. The power of radiation shows the asymmetric dependence on the horizontal spin components. The symmetry is restored for the ultra-relativistic and non-relativistic motions. At the same time, the first case shows the presence of radiation at either spin orientation whereas in the second case the radiation is absent when ς || H . In the case of uniform motion, the power expression obtained in the study coincides with the ones known from both the classical and the quantum theory.
