Abstract: We report the first observation of translationally cold (similar to 90 mu K) Rb-2 molecules. They are produced in a magneto-optical trap in their triplet ground state. The detection is performed by selective mass spectroscopy after two-photon ionization into Rb-2(+), resonantly enhanced through the intermediate a(3)Sigma(u)(+) –> 2(3)Pi(g) molecular band. The two rubidium isotopes present very different types of behavior that an interpreted in terms of their respective collisional properties.
