Using the theoretical Formalism of Y. Ohashi and A. Griffin, Phys. Rev A67 (2003), we have evaluated the scattering length and effective range of an attractive square well potential for ultracold atomic gases. We have also evaluated the energy of the bound state Em. Our theoretical results show that for any potential with large positive scattering length has a bound state just below the continuum threshold of energy given by Em. Our theoretically evaluated results are in good agreement with other theoretical workers.
