    The dynamics of two coupled soliton solutions of the nonlinear Schrodinger equation with a saturable nonlinearity is investigated It is shown by means of a variational method and by direct numerical calculations that two well-separated solitons can orbit around each other, if their initial velocity is equal to a certain critical velocity. For initial velocities below and above this critical velocity the solitons merge and separate, respectively. The analytical calculations are based on the assumption of a large separation distance, and under this assumption numerical simulations confirm the main results. (C) 1998 Elsevier Science B.V.
