Abstract A combination of two programs is described for the study of the class of central potentials V(r) = - D + Σ^∞ _(k=0)V_k b^k r^(2k+2), V_0= w^2> 0, which is of special interest in theoretical physics. The first program uses the Hypervirial Theorems (HVT) and the Hellmann-Feynman Theorem (HFT) to calculate approximate analytic expressions for the non-relativistic energy eigenvalues, the expectation values of the potential and the kinetic energy operator, and the expectation values of th...
