Magnetic trapping of metastable [Formula Presented] atomic strontium

Academic Article


  • We report the magnetic trapping of metastable [Formula Presented] atomic strontium. Atoms are cooled in a magneto-optical trap (MOT) operating on the dipole-allowed [Formula Presented] transition at 461 nm. Decay via [Formula Presented] continuously loads a magnetic trap formed by the quadrupole magnetic field of the MOT. Over [Formula Presented] atoms at a density of [Formula Presented] and temperature of 1 mK are trapped. The atom temperature is significantly lower than what would be expected from the kinetic and potential energies of atoms as they are transferred from the MOT. This suggests the occurrence of thermalization and evaporative cooling in the magnetic trap. © 2003 The American Physical Society.
