Aa. Viggiano et al., MOBILITIES AND INTERACTION POTENTIALS FOR THE O-HE AND O--HE SYSTEMS(), The Journal of chemical physics, 98(8), 1993, pp. 6483-6487
Mobilities of O+ and O- ions in He gas have been measured as a functio
n of electric field strength at temperatures from 93 to 568 K. The res
ults are compared with previous work, and analyzed in terms of a tempe
rature-field strength scaling rule and the O+-He and O--He potentials.
Emphasis is placed on how much information on the potentials can be o
btained from simple features of the mobility curve without extensive n
umerical computation.
