Abstract
We have studied effects of interspecies attraction in a Fermi-Bose mixture over a large regime of particle numbers in the system. We report on the observation of a mean-field driven collapse at critical particle numbers of atoms in the condensate and atoms consistent with mean-field theory for a scattering length of . For large overcritical particle numbers, we see evidence for revivals of the collapse. Part of our detailed study of the decay dynamics and mechanisms is a measurement of the () three-body loss coefficient , which is an important parameter for dynamical studies of the system.
