Abstract
We study the stability and dynamics of vortices in a two-species condensate as prepared in the recent JILA experiment (M. R. Andrews et al., Phys. Rev. Lett. 83 (1999) 2498). We find that of the two available configurations, in which one specie has vorticity m=1 and the other one has m=0, only one is linearly stable, which agrees with experimental results. However, it is found that in the unstable case, the vortex is not destroyed by the instability but suffers a revival process in which it is transfered from one of the condensate species to the other. This prediction can be checked in current experiments
