Study of Positive Helium Ions in Superfluid Helium-4

We report on studies of positive ions in superfluid helium-4. In addition to the positive ion that has been previously studied, we have been able to detect two more positive ions with slightly different mobility, and the results show some evidence for a third additional ion.
