    "abstract": "We have observed thermalization by elastic collisions of magnetically trapped\nmetastable helium atoms. Our method directly samples the reconstruction of a\nthermal energy distribution after the application of an RF knife. The\nrelaxation time of our sample towards equilibrium gives an elastic collision\nrate constant close to the unitarity limit.",
