WebMar 1, 1997 · In our experiments we start with sodium atoms effusing from an oven at a temperature of 600 K (a velocity of 800 m s -1) and a density of about 10 14 cm -3. Over a distance of 0.5 m the atoms are first slowed with a laser beam to a speed of around 30 m s -1. This is slow enough for around 10 10 atoms to be captured in a magneto-optical trap. WebCo-located gases of K and Rb are simultaneously laser-cooled, optically trapped and evaporatively cooled to a high phase-space density. Next, pairs of atoms from this mixed …
