Several authors have treated kinetic effects associated with the ion-acoustic soliton; e.g., Ott and Sudan investigated linear electron Landau damping and Karpman and Lotko have looked at damping due to ion reflection. Here an O'Neil-type frozen wave calculation that includes effects associated with electron orbits in a soliton is presented. This calculation differs from previous ones in that the usual three time scale argument is made: ..omega../sub p/e >>..omega../sub b/e >>..gamma../sub L/. The orbit effects included in this ordering become important at the modest amplitude ePhi/T/sub e/> or approx. =(m/sub e//m/sub i/)./sup 2/ Saturation at finite amplitude is predicted.
