摘要：
The exact solutions of two-dimensional Schrodinger equation with the position-dependent mass for a hard-core potential are obtained. The eigenvalues related to the position-dependent masses mu(1) and mu(2), the potential well depth V-0 and the effective range r(0) can be calculated by the boundary condition. We generalize this quantum system to three-dimensional case. The special cases for l = 0, 1 are studied in detail. For l = 0 and c = 0, we find that the energy levels will increase with the parameters mu(2), V-0 and r(0) if mu(1) > mu(2). 2005 Published by Elsevier B.V.
