Evaporative cooling of magnetically trapped atomic molybdenum

We have magnetically trapped and evaporatively cooled atomic molybdenum. Using a cryogenic helium buffer gas, 2×10^10 molybdenum atoms are loaded into a magnetic trap at an initial temperature of 500 mK. We measure a molybdenum inelastic rate constant of gin = (1.2±0.6)×10^−12cm^3s^ −1 for the initial conditions after loading. The molybdenum atoms are cooled by adiabatic expansion and forced evaporation to 200 mK.Physic
