Reactions of ultracold alkali-metal dimers.

Zuchowski, Piotr S. and Hutson, Jeremy M. (2010) 'Reactions of ultracold alkali-metal dimers.', Physical review A., 81 (6). 060703.


We investigate the energetics of reactions involving pairs of alkali-metal dimers. Atom exchange reactions to form homonuclear dimers are energetically allowed for some but not all of the heteronuclear dimers. We carry out high-level electronic structure calculations on the potential energy surfaces of all the heteronuclear alkali-metal trimers and show that trimer formation reactions are always energetically forbidden for low-lying singlet states of the dimers. The results have important implications for the stability of quantum gases of alkali-metal dimers.
