抄録

Aiming at constructing a compact magneto-optical trap for metastable helium gas (He^*), we have produced cold He^* atoms in a simple helium cryostat. The He^* atoms are generated by an RF discharge in a vapor above a liquid He bath, which is cooled to 1.2 K by pumping the cryostat. The temperature and density of the He^* atoms are estimated to be 15 K and 10¹¹ atoms/cm³, respectively, from laser spectroscopy of the 2³S₁-2³P_2,1 transitions.
