✦ Synopsis

In a crossed molecular beam experiment differential time-of-flight spectra have been measured for (NH,),

He collisions at E = 108 meV. The energy transfer in the backward direction is large. AE/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.

In the collision of Br + with Kr there is considerable transfer of translational to electronic energy and vice versa. This energy transfer is modelled as a Landau-Zener process at the points where the potential energy curves of the various electronic states of the halogen positive ion complex (KrBr
