hydrogen
... Ions such as He+ and Li2+ are hydrogen-like since they also have only a single electron. In each case the mass of the electron is much less the nuclear mass, therefore, we will assume a stationary nucleus exerting an attractive force that binds the electron. This is the Coulomb force with correspond ...

The variational principle and simple properties of the ground
... particular, it is shown that the ground-state wave function can be taken to be real and non-negative, and that it cannot be degenerate. Other consequences for the angular momentum and the parity of the ground state are also presented. There is a vast literature on the properties of the groundstate w ...
