Using a model that describes the dynamics of the trapped chromium cloud during evaporation, we find gel= 2.15 +2.5,−1.2 10−10 cm3 / s and gin = 1.36 +1.2,−0.7 10−12 cm3 / s, consistent with theory but in disagreement with previously reported measurements.en-USJournal Article2017-06-2310.1103/PhysRevA.75.062706
