Abstract
This paper describes measurements of the cross section for capture of negative ions by vortex lines in He II and of the mobility of the negative ion, as a function of both pressure and temperature. The first of these measurements is used to derive the variation of the negative-ion radius with pressure. The bubble model of the negative ion is then discussed in the light of the derived radii and an explanation of the mobility measurements is given. Certain null results on positive ions are also presented.Keywords
