Abstract

• nelastic collision rates for ultracold ⁸⁵Rb atoms in the F=2, m_f=−2 state have been measured as a function of magnetic field. At 250 gauss (G), the two- and three-body loss rates were measured to be K₂=(1.87±0.95±0.19)×10^-14 cm³/s and K₃=(4.24+0.70−0.29±0.85)×10^-25 cm⁶/s, respectively. As the magnetic field is decreased from 250 G towards a Feshbach resonance at 155 G, the inelastic rates decrease to a minimum and then increase dramatically, peaking at the Feshbach resonance. Both two- and three-body losses are important, and individual contributions have been compared with theory.
