Inelastic collisions near Feshbach resonances in ultra-cold 7Li

This study investigates two- and three-body losses in the vicinity of two Feshbach resonances on the |F=1,mF=0> state. The successful achievement of inelastic processes in ultracold 7Li Bose Einstein condensate near the Feshbach resonances is reported in detail. This investigation reveals that inelastic collisions are very strong in-between the resonances, despite the presence of zero crossing point where scattering length disappears.
