Atomic and Molecular Physics

Neutral sodium atoms have been continuously loaded into a 0.1-K-deep superconducting magnetic trap with laser light used to slow and stop them. At least 1 \ifmmode\times\else\texttimes\fi{} ${10}^{9}$ atoms were trapped with a decay time of 2\textonehalf{} min. The fluorescence of the trapped atoms was studied as a function of time; possible loss mechanisms from the trap are discussed.
