Abstract
A charged particle stopped in superfluid helium produces both excitati ons in the liquid (phonons and rotons) and photons by fluorescence. Us ing a calorimeter with a response time of 50 mu s we are able to time- resolve in a single detector signals from the photons and from the exc itations of the liquid at 25 mK. The implications of this observation for the detection of low energy solar neutrinos are discussed.
