Abstract
We demonstrate photoassociation (PA) of ultracold fermionic 87Sr atoms. The binding energies of a series of molecular states on the 1Σ^+u 5s2 1S0+5s5p 1P1 molecular potential are fit with the semiclassical LeRoy-Bernstein model, and PA resonance strengths are compared to predictions based on the known 1S0+1S0 ground state potential. Similar measurements and analysis were performed for the bosonic isotopes 84Sr and 86Sr, allowing a combined analysis of the long-range portion of the excited-state potential and determination of the 5s5p 1P1 atomic state lifetime of 5.20 pm 0.02 ns. The results enable prediction of PA rates across a wide range of experimental conditions.
