Abstract

In a crossed molecular beam experiment differential time-of-flight spectra have been measured for (NH3)2 + He collisions at E = 108 meV. The energy transfer in the backward direction is large, Δ E E ≈ 0.60. Only about half of it can be explained by simple rotational-vibrational excitation of the dimer without incorporating the internal degrees of freedom of each individual monomer.
