Determination of the Scattering Lengths of 39 K from 1 u Photoassociation Lineshapes

December 1, 1999
Author(s)
Carl J. Williams, Eite Tiesinga, Paul S. Julienne, H Wang, W C. Stwalley, P L. Gould
We report threshold scattering properties for 39K(f = 1) atoms obtained from analysis of experimental photoassociation spectra of the purely long-range 39K 21 u state. The existence of hyperfine structure in the excited K 2 1 u state and a knowledge of the

Elastic and Inelastic Collisions of Cold Spin-Polarized 133 Cs Atoms

August 17, 1998
Author(s)
P J. Leo, Eite Tiesinga, Paul S. Julienne, T G. Walker
We present theoretical calculations of thermally averaged elastic cross sections and spin relaxation rates in the temperature range 1 {micro}K to 300 {micro}K for magnetically trapped doubly polarized Cesium atoms. The calculations reproduce the recent

Elastic and Inelastic Collisions of Cold Spin-Polarized 133 Cs Atoms

August 1, 1998
Author(s)
P J. Leo, Eite Tiesinga, Paul S. Julienne, D K. Walter, S Kadlecek, T G. Walker
We present theoretical calculations of thermally averaged elastic cross sections and spin-relaxation rate coefficients in the temperature range 0.1 to 300 K for Magnetically trapped doubly polarized cesium atoms. The calculations reproduce the recent

Atomic Collisions in Ultracold Atomic Gases

July 1, 1997
Author(s)
Paul S. Julienne, Kevin Jones, Paul D. Lett, William D. Phillips, Eite Tiesinga, U Volz, Carl J. Williams
Cold collisions between trapped atoms are very important in the context of Bose-Einstein condensation. The meaning of the scattering length, and its determination through the precision measurements of photoassociation spectroscopy, are described. This is
