Abstract

It has been shown that energetic neutral excitations are produced when a tritium (β− emitter) source is immersed in He II. These neutrals have the same characteristics as those observed by Surko and Reif for a 210 Po (α emitter) source. However, a strong electric field in the ionization region of the source is required in the tritium case to produce neutrals. Using this effect it is possible to produce pulses of neutrals and obtain information about their physical properties. We suggest a three-level decay scheme with an intermediate state to explain our experimental results.
