2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/154007We report on the observation of Feshbach resonances in an ultracold mixture of two fermionic species, 6Li and 40K. The experimental data are interpreted using a simple asymptotic bound state model and full coupled channels calculations. This unambiguously assigns the observed resonances in terms of various s- and p-wave molecular states and fully characterizes the ground-state scattering properties in any combination of spin states.4 pages, 4 figures, 1 tableOther Condensed Mattertext
