The method consists in measuring the decay of X(4660) into $\\eta D^* \\bar D^*$, determining the binding energy with respect to the $D^* \\bar D^*$ threshold from the shape of the $D^* \\bar D^*$ invariant mass distribution. A complementary method consists in looking at the inclusive $X(4660) \\to \\eta X$ decay, searching for a peak in the $X$ invariant mass distribution given by the missing X(4660), $\\eta$ mass.
