    "abstract": "Based on an experimental study of two-body and three-body collisions in\nultracold strontium samples, a novel optical-sympathetic cooling method in\nisotopic mixtures is demonstrated. Without evaporative cooling, a phase-space\ndensity of $6\\times10^{-2}$ is obtained with a high spatial density that should\nallow to overcome the difficulties encountered so far to reach quantum\ndegeneracy for Sr atoms.",
