Abstract

We report the experimental determination of the interspecies s-wave scattering length (a34) between the 23S1(F=3/2,mF=3/2) state of He∗3 and the 23S1(mJ=1) state of He∗4. We determine a34 by inducing oscillations in a trapped Bose-Einstein condensate of He∗4 and measuring the damping rate of these oscillations due to the presence of He∗3 atoms. Our measured value of a34=30±4 nm is in good agreement with theoretical predictions. The knowledge of this scattering length is important for many fundamental experiments between these helium isotopes.
