Triplet satellite bands of KRb molecule in the far blue wings of K and Rb resonance lines
In a hot metal vapor K-Rb mixture usually spectral phenomena of both K2 and Rb2 dimers appear together with KRb bands. Sometimes spectral overlaps preclude a clear observations of the satellite bands in the vicinity of the first resonance lines. However, in the case of potassium-rubidium vapor mixture the resonance lines are located within 765-795 nm spectral region, and the very far blue quasistatic wing can be investigated in detail. We found beside K and Rb satellite bands a three distinct satellite bands at 730 nm and a single shoulder at 755.5 nm that we asigned to KRb heteronuclear molecule. The interpretation of these KRb satellite bands is very similar to the interpretation of K and Rb satellite bands [1]. This will be discussed in terms of the recent ab initio calculations of the relevant potential curves. Quite recently Gabbanini et al. [2] have detected ultracold Rb2 molecules by two- photon resonance enhanced ionization at about 600 nm. We believe that resonance enhanced ionization using 755.5 nm satellite band wavelength can be useful in the detection of ultracold KRb molecules. ______________________________ [1] R. Beuc, S.
