Résumé

We have observed thermalization by elastic collisions of magnetically trapped metastable helium atoms. Our method directly samples the reconstruction of a thermal energy distribution after the application of a RF knife. The relaxation time of our sample toward equilibrium gives an elastic collision rate constant of [Formula Presented] at a temperature of 1 mK. This value is close to the unitarity limit.
