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…

Classical and Quantum Analysis of One Dimensional Velocity Selection for Ultracold Atoms
J. K. Fox, H. A. Kim, S. R. Mishra +5
We discuss a velocity selection technique for obtaining cold atoms, in which all atoms below a certain energy are spatially selected from the surrounding atom cloud. Velocity selec…
