title: Interaction of a soliton with a continuous wave packet.
abstract: We analyze the scattering of a soliton from a continuous wave packet of arbitrary shape in a fiber, theoretically as well as numerically. Solitons recover their original shapes and velocities after collisions and the effect of collisions is described by the change of velocities of solitons. The theoretical predictions based on a WKB-type approximation are in a good agreement with numerical results.
