Abstract
Using the complex scaling transformation we calculate the tunneling lifetime of a condensate inside a magnetic/optical trap. We show that by varying the scattering length, the external potential acts like a 'selective membrane' which controls the direction of the flux of the cold atoms through the barriers and thereby controls the size of the stable condensate inside the trap.
