Abstract
Evaporative cooling under microgravity is investigated in the free-fall experiment of ${}^{87}$Rb atoms optically trapped from a temporarily dark magneto-optical trap in the drop tower in Bremen. The efficiency of evaporation is determined to be equal, with and without the effect of gravity.
