We report the first observation of translationally cold (90 microK) Rb2 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 Rb2 +, resonantly enhanced through the intermediate molecular band. The two rubidium isotopes present very different types of behavior that are interpreted in terms of their respective collisional properties.

Abstract
We report the first observation of translationally cold (90 microK) Rb2 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 Rb2 +, resonantly enhanced through the intermediate molecular band. The two rubidium isotopes present very different types of behavior that are interpreted in terms of their respective collisional properties.File in questo prodotto:
