Soft-core Coulomb potentials and Heun's differential equation
Richard L. Hall, Nasser Saad, K. D. Sen
Schroedinger's equation with the attractive potential V(r) = -Z/(r^q+ b^q)^(1/q), Z > 0, b > 0, q >= 1, is shown, for general values of the parameters Z and b, to be reducible to t…

Energies and wave functions for a soft-core Coulomb potential
Richard L. Hall, Nasser Saad, K. D. Sen +1
For the family of model soft Coulomb potentials represented by V(r) = -\frac{Z}{(r^q+β^q)^{\frac{1}{q}}}, with the parameters Z>0, β>0, q \ge 1, it is shown analytically that the p…

Relativistic effects on information measures for hydrogen-like atoms
K. D. Sen, Jacob Katriel
Position and momentum information measures are evaluated for the ground state of the \emph{relativistic} hydrogen-like atoms. Consequences of the fact that the radial momentum oper…
