Langevin ion-mobility theories

[länzh·van ¦ī‚än mō′bil·əd·ē ‚thē·ə·rēz] (electronics) Two theories developed to calculate the mobility of ions in gases; the first assumes that atoms and ions interact through a hard-sphere collision and have a constant mean free path, while the second assumes that there is an attraction between atoms and ions arising from the polarization of the atom in the ion's field, in addition to hard-sphere repulsion for close distances of approach.
