| Abstract: | We present an experimental and theoretical study of atom-molecule collisions in a mixture of cold, trapped N atoms and NH molecules at a temperature of ∼600 mK. We measure a small N + NH trap loss rate coefficient of \(\kappa_{loss^{(N+NH)}}\) = 9(5)(3)×10\(^{-13}\) cm\(^3\) s\(^{-1}\). Accurate quantum scattering calculations based on ab initio interaction potentials are in agreement with experiment and indicate the magnetic dipole interaction to be the dominant loss mechanism. Our theory further indicates the ratio of N + NH elastic-to-inelastic collisions remains large (>100) into the mK regime. |
