Observation of Efimov Universality across a Non-Universal Feshbach Resonance in \textsuperscript{39}K

Xin Xie, Michael J. Van de Graaff, Roman Chapurin +6

We study three-atom inelastic scattering in ultracold \textsuperscript{39}K near a Feshbach resonance of intermediate coupling strength. The non-universal character of such resonan…
