We numerically study the behavior of collapsing and exploding condensatesusing the parameters of the experiments by E.A. Donley et al. [Nature,  412, 295, (2001)]. Our studies are based on a full three-dimensionalnumerical solution of the Gross-Pitaevskii equation (GPE) including three bodyloss. We determine the three body loss rate from the number of remnantcondensate atoms and collapse times and obtain only one possible value whichfits with the experimental results. We then study the formation of jet atoms byinterrupting the collapse and find very good agreement with the experiment.Furthermore we investigate the sensitivity of the jets to the initialconditions. According to our analysis the dynamics of the burst atoms is notdescribed by the GPE with three body loss incorporated.Comment: 9 pages, 10 figure
