The eigenfunctions and eigenvalues of the Schrodinger equation witha ring-shaped non-spherical oscillator are obtained. A realization of the ladder operators for the radial wave functions is studied. It is found that these operators satisfy the commutation relations of an SU(1, 1) group. The closed analytical expressions for the matrix elements of different functions p and rho (d)/(drho) with rho = r(2) are evaluated. (C) 2004 Published by Elsevier B.V.
