Magnetic Trapping of Atomic Nitrogen (14N) and Cotrapping of NH (X3sigma)

Abstract

We observe magnetic trapping of atomic nitrogen (14N) and cotrapping of ground-state imidogen (14NH,X3sigma). Both are loaded directly from a room-temperature beam via buffer gas cooling. We trap approximately1 x 10(11) 14N atoms at a peak density of 5 x 10(11) cm3 at 550 mK. The 12 +/- 1/e lifetime of atomic nitrogen in the trap is consistent with a model for loss of atoms over the edge of the trap in the presence of helium buffer gas. Cotrapping of 14N and 14NH is accomplished, with 10(8) NH trapped molecules at a peak density of 10(8) cm3.
