Abstract
This work observes deviations from the Born-Oppenheimer approximation already from ultracold diatomic collisions of K. To improve the potential energy curves, the most recent available data from all inter- and intra-isotope combinations of K as well as three newly measured $\mathit{\text{d}}$-wave Feshbach resonances in ${}^{39}\text{K}$ are used.
