Te. Liolios et Me. Grypeos, THE JACOBI EIGENFUNCTIONS AND THE QUANTUM-MECHANICAL HYPERVIRIAL THEOREMS METHOD FOR BOUND-STATE PROBLEMS, Journal of physics. A, mathematical and general, 30(10), 1997, pp. 325-330
The Jacobi eigenfunctions are suitably adjusted by means of the hyperv
irial theorems (HVT) scheme in order to obtain, in many cases, a very
satisfactory analytic approximation of the s-state eigenfunctions of t
he radial Gaussian potential. The results obtained show that the HVT s
cheme is a powerful method for obtaining (analytically) not only appro
ximate eigenvalues but also the corresponding eigenfunctions.
