  A new scheme has been proposed to solve the B.E. condenstates in terms of
Green's function approach. It has been shown that the radial wave function of
two interacting atoms, moving in a common harmonic oscillator potential
modified by an effective interaction,satifies an integral equation whose kernel
is separable.The solution of the integral equation can be written in terms of
the harmonic oscillator wave functions. The ground state wave function of the
system can be written in terms of these solutions.
