The eigenvalues of the radial Schr6dinger equation are calculated very accurately by obtaining exact upper and lower bounds. By truncating the usual unbounded domain [0,cx~) of the system to a finite interval of the form [0,g], two auxiliary eigenvalue problems are defined. It is then proved that th
