Abstract
We report the experimental evidence of the sympathetic cooling of K with Rb down to 1 K, obtained in a novel tight confining magnetic trap. This allowed us to perform the first direct measurement of the elastic cross section of K below 50 K. The result obtained for the triplet scattering length, Bohr radii, agrees with previous results derived from photoassociation spectra and from Feshbach spectroscopy of K.
