Magnetic-field dependent trap loss of ultracold metastable helium
J. S. Borbely, R. van Rooij, S. Knoop +1
We have experimentally studied the magnetic-field dependence of the decay of a Bose-Einstein condensate of metastable 4He atoms confined in an optical dipole trap, for atoms in the…
Cold and trapped metastable noble gases
Wim Null Vassen, Claude Cohen-Tannoudji, Michèle Leduc +7
We review experimental and theoretical work on cold, trapped metastable noble gases. We em- phasize the aspects which distinguish work with these atoms from the large body of work…
Frequency metrology in quantum degenerate helium: Direct measurement of the 2 3S1 - 2 1S0 transition
R. van Rooij, J. S. Borbely, J. Simonet +4
Precision spectroscopy of simple atomic systems has refined our understanding of the fundamental laws of quantum physics. In particular, helium spectroscopy has played a crucial ro…
