Abstract
We identify an eigenvalue associated with a dilute two-species Bose-Ei nstein condensate as the determiner of condensate stability. It plays the same role as the sign of scattering length in a one-species conden sate. We predict that there is a range of interspecies interaction str ength in which a sodium-rubidium mixture can be stable in a harmonic t rap. [S0031-9007(97)04343-3].
