The Landau-Lifshitz equation is derived as a first-order iteration of the L
orentz-Dirac equation for the charged particle. In those cases with null el
ectromagnetic field's gradient, the Landau-Lifshitz gives the so named Herr
era equation. A general method for the solution of the latter equation is p
resented and applied to the motion of a particle in a uniform electromagnet
ic field. (C) 1999 American Institute of Physics. [S0022-2488(99)01610-2].
