摘要：

We show that solitons of the fourth order nonlinear Schrodinger equation may be both stationary and radiating, depending on the sign of the coefficient before the fourth derivative. A transition from one case to the other is investigated. An asymptotic solution describing soliton radiation is obtained and the soliton damping rate due to the radiation is calculated.
