Abstract:

Measurements are described of the transfer of momentum from a beam of normally incident N2 ions to a copper target forming one arm of a sensitive torsion balance. As the incident ion energy is increased, the accommodation coefficient for the normal component of momentum falls rapidly from unity for 4 eV ions to a minimum value of 0.4 for about 7 eV ions, then increases gradually to an asymptotic value of 0.7 for 50-100 eV ions.
