Specific emphasis is put on the role played by the interaction in the final $\\bar \\Lambda \\Lambda$ system which is taken into account rigorously. For that interaction a variety of $\\bar \\Lambda \\Lambda$ potential models is employed that have been constructed for the analysis of the reaction $\\bar p p \\to \\bar \\Lambda \\Lambda$ in the past. The enhancement of the effective form factor for energies close to the $\\bar \\Lambda \\Lambda$ threshold, seen in pertinent experiments, is reproduced.
