Abstract

We present the results of the first mobility measurements in superfluid helium for negative ions of different elements. Various negative ions like Cl-, F- and I- were produced by laser ablation from targets consisting of NaCl, NaF, NaI, LiF and KCl immersed in a He-4 bath. In addition to negative ions of halogen ablated from salts we have studied the mobility of the negative metallic ions Ba- and Ga- implanted into superfluid helium. (C) 2003 Elsevier Science B.V.
