Query: Radiation Reaction for a Charged Brownian Particle   As it is known a model of a charged particle with finite size is a good tool
to consider the effects of self- action and backreaction, caused by
electromagnetic radiation. In this work the "size" of a charged particle is
induced by its stochastic Brownian vibration. Appropriate equation of
particle's motion with radiation force is derived. It is shown that the
solutions of this equation correctly describe the effects of radiation
reaction.
