Abstract

We prepare mixtures of ultracold \(^{39}\)K atoms in various hyperfine spin states and \(^{23}\)Na\(^{39}\)K molecules in an optical dipole trap at a fixed magnetic field and study inelastic two-body atom-molecule collisions. We observe atom-molecule loss that is hyperfine dependent with a two-body loss rate far below the universal limit. We analyze the two-body loss dynamics based on the derivation of general and easy applicable analytic solutions for the differential equations describing the loss of an arbitrary number \(\gamma\) of particles in a single collisional event.
