Abstract

We have measured the two body loss rate in a magneto-optical trap containing triplet metastable He atoms. We find a rate constant β = 3 × 10^-8 cm³/s at a -8 MHz detuning, with an uncertainty of a factor 2. This measurement is in disagreement with a recent experiment which measures the absolute, ion-producing collision rate, but agrees with several other published measurements.
