✦ Synopsis

Classical trajectory calculations for the rotational excitation'of CO and Hz by collision &ith He have been carried out and compared to the accurate qu&~m mechanics1 cfculations of other workers The grecment is rasonably encourngig, although some irther&t limitations of this strictly classical appro~h are observed ana discussed.

Charge transfer and hydrogen atom pickup cross sections are reported for N+-H20( D,O) collisions at center-of-mass energies between I and 25 eV. Time-of-flight measurements were performed to determine the charge transfer product ion kinetic energies. The exothermic charge transfer proceeds rapidly
