- Abstract: We demonstrate photoassociation (PA) of ultracold fermionic $^{87}$Sr atoms.
The binding energies of a series of molecular states on the $^1\Sigma^+_u$
$5s^2\,^1$S$_0+5s5p\,^1$P$_1$ molecular potential are fit with the
semiclassical LeRoy-Bernstein model, and PA resonance strengths are compared to
predictions based on the known $^1$S$_0+^1$S$_0$ ground state potential.
Similar measurements and analysis were performed for the bosonic isotopes
$^{84}$Sr and $^{86}$Sr, allowing a combined analysis of the long-range portion
of the excited-state potential and determination of the $5s5p\,^1$P$_1$ atomic
state lifetime of $5.20 \pm 0.02$ ns. The results enable prediction of PA rates
across a wide range of experimental conditions.

The total energy functional correctly dissociates the H-H bond and yields absolute errors of 0.002 $rA$, 0.19 eV, and 13 cm-1$ relative to experiment at the tight binding computational cost.

We investigate the production of all-optical $39$K Bose-Einstein condensates with different scattering lengths using a Feshbach resonance near $33$ G.
