    "abstract": "An unexpected prediction of classical electrodynamics is that a charge can\naccelerate before a force is applied. We would expect that a preaccelerated\ncharge would radiate so that there would be spontaneous preradiation, an\nacausal phenomenon. We reexamine the subtle relation between the Larmor formula\nfor the power radiated by a point charge and the Abraham-Lorentz equation and\nfind that for well-behaved external forces acting for finite times, the charge\ndoes not radiate in time intervals where there is preacceleration. That is, for\nthese forces preradiation does not exist even though the charge is\npreaccelerated. The radiative energy is emitted only in time intervals when the\nexternal force acts on the charge.",
