AWhat changed
Barry and colleagues confined strontium monofluoride molecules in a three-dimensional magneto-optical trap. Reversing the trapping conditions and observing the response of displaced clouds helped test whether the trap supplied a restoring force. The authors estimated about 400 molecules and reported a 56 ± 4 millisecond lifetime in the stated conditions.
Scientific scope
Barry and colleagues confined strontium monofluoride molecules in a three-dimensional magneto-optical trap. Reversing the trapping conditions and observing the response of displaced clouds helped test whether the trap supplied a restoring force. The authors estimated about 400 molecules and reported a 56 ± 4 millisecond lifetime in the stated conditions. The molecule count depends on fluorescence and scattering-rate calibration. Temperature estimates depend on the experimental model and imaging; the sample was not a quantum-degenerate gas. This trap is a later contribution than the earlier one-dimensional molecular-beam cooling experiment.
