- Abstract
- We perform a comparative study of the formation of ultracold rubidium
dimers in their ground state with both 85Rb and 87Rb isotopes. Ultracold
rubidium molecules are created through photoassociation of ultracold atoms
into rovibrational levels of the 0+u (5S1/2 + 5P1/2) excited state, which interact
through resonant coupling (Dion et al 2001 Phys. Rev. Lett. 86 2253) with
rovibrational levels of the 0+u (5S1/2 + 5P3/2) excited state. The photoassociated
levels decay by spontaneous emission down to rovibrational levels of the X1Sigma+g
ground state. The resonant coupling is expected to enhance the formation
of ultracold molecules in low-lying ground-state levels. By modelling the
ionization spectrum of these ultracold molecules, we show that this coupling
is larger for 87Rb2 molecules than for 85Rb2 molecules. (literal)
