Recoil energy distributions, phase space

The recoil distribution for this system is rather interesting we find that the products are formed with 30% of the total energy in translation. This result is quite close to statistical predictions and, in fact, the phase space volume associated with the high frequency H-atom motions in the CH3 fragment is so small that the experimental data do not allow one to conclude the extent to which vibrational energy is shared among the modes of the collision complex.
