Shift operators are derived for s states of the Hulthén potential. These operators are used to obtain energy eigenvalues and normalized coordinate‐space wave functions for bound s states. The condition for the existence of these states is deduced from the Hellmann–Feynman theorem, and this theorem together with the hypervirial theorem are used to calculate certain expectation values.
