Abstract
The Bose condensate model is used to elucidate the interaction of vortex li nes with impurities. Three-dimensional numerical integration of the coupled nonlinear Schrodinger equations, which describe the evolution of the wave functions of the Bose condensate and an impurity, are used to study the pro cess of capture of the impurity by a rectilinear vortex and to elucidate th e binding energy. Kelvin waves are generated during capture.
