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

^{14}\mathrm{N}

and

^{14}\mathrm{N}\mathrm{H}

is accomplished, with

NH trapped molecules at a peak density of ${10}^{8}\phantom{\rule{0.3em}{0ex}}{\mathrm{cm}}^{\ensuremath{-}3}$.
