TL;DR: The observed Feshbach resonances in an ultracold mixture of two fermionic species are interpreted using a simple asymptotic bound state model and full coupled channels calculations and unambiguously assigns the observed resonances to various s- and p-wave molecular states.

TL;DR: The photoassociation rate constant increases linearly with intensity, even where it is predicted that many-body effects might limit the rate.

TL;DR: In this paper, the lifetime τ(P3/2) = 16.230(16) ns was derived from molecular spectroscopy of the Na2 purely long-range 0−g state.

TL;DR: In this article, it was shown that a laser far detuned from an excited molecular level near the frequency of the atomic intercombination transition can be used to tune the scattering length for the collision of ground-state alkaline-earth-metal atoms using an optical Feshbach resonance.

TL;DR: Semianalytic expressions for scattering probabilities of cold trapped atoms in the presence of two weak, independently tunable laser fields, both tuned near molecular resonances are presented.
