Lifetime of weakly-bound dimers of ultracold metastable helium studied by photoassociation
Steven Moal, Maximilien Portier, Nassim Zahzam +1
We describe two-photon photoassociation (PA) experiments operated in an ultracold gas of metastable He atoms in the state. Atom-molecule dark resonances as well as…
Analysis of light-induced frequency shifts in the photoassociation of ultracold metastable helium atoms
Maximilien Portier, Steven Moal, Jaewan Kim +3
We present an exhaustive analysis of the light-induced frequency shifts of the photoassociation lines of ultracold metastable 4He* atoms in a magnetic trap. The measurements of the…
Accurate determination of the scattering length of metastable Helium atoms using dark resonances between atoms and exotic molecules
S. Moal, M. Portier, J. Kim +4
We present a new measurement of the s-wave scattering length a of spin-polarized helium atoms in the 2^3S_1 metastable state. Using two-photon photoassociation spectroscopy and dar…
Frequency shifts of photoassociative spectra of ultracold metastable Helium atoms : a new measurement of the s-wave scattering length
J. Kim, S. Moal, M. Portier +3
We observe light-induced frequency shifts in one-color photoassociative spectra of magnetically trapped He atoms in the metastable state. A pair of ultracold spin-…
