The loss of ultracold trapped atoms in the vicinity of a Feshbach resonance is treated as a two-stage reaction, using the Breit-Wigner theory. The first stage is the formation of a resonant diatomic molecule, and the second one is its deactivation by inelastic collisions with other atoms. This model is applied to the analysis of recent experiments on {sup 87}Rb, leading to an estimated value of 7x10{sup -11} cm{sup 3}/s for the deactivation rate coefficient.
