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