Detection of Li atoms scattered from a magneto-optical trap by using slow and cold molecular beams — •Bernhard Ruff, Matthias Strebel, Marcel Mudrich, and Frank Stienkemeier — Physikalisches Institut, Universität Freiburg, Herman-Herder-Str. 3, D-79104 Freiburg im Breisgau

Slow beams of cold molecules or atoms produced by a rotating nozzle are scattered with magneto-optically trapped Li atoms. Detection of Li by means of surface ionization on a hot ribbon allows to observe elastic and inelastic scattering processes as a function of kinetic energy down to about 1 meV. Technical details regarding the slow molecular beam source, the ultra-cold scattering target and the detection schemes are discussed. Furthermore, first measurements with different atomic and molecular beams are presented.
