Storing and cooling simultaneously lithium and sodium atoms in a two-species magneto-optical trap, rate coefficients for collisions between these two atomic species were determined. The experiments were performed at different trap depths, thus for Li atoms the trap losses due to finestructure changing collisions could be distinguished from losses due to radiative escape. The rate coefficient for collisions between sodium and lithium atoms shows also a step when increasing the trap depth. The formation of cold heteronuclear molecules is claimed.

In the performed experiment we trap simultaneously in the Magneto-Optical Trap cold atoms of 7Li with cold sodium atoms and cold 6Li atoms with cold 23Na atoms. We investigated in detail heteronuclear interactions between cold isotopes of lithium atoms and cold sodium atoms in presence of the laser light.

The frequency dependence of the collisional trap loss rate for ultracold sodium atoms held in a magneto-optical trap was measured using the optical catalysis technique. The experiment was carried out near the 3S
