[en] By means of computer the stability of one-dimensional soliton solutions of the relativistically invariant model of complex scalar field with the current x current self-interaction is investigated. As a result, the stability region of particle-like solutions has been found. It is shown that in the stability region the particle-like solutions satisfy the necessary conditions of stability obtained earlier when studying the solution stability within this model in the linear approximation of perturbation theory
