##### 9: 18.39 Physical Applications
For (18.39.2) to have a nontrivial bounded solution in the interval $-\infty, the constant $E$ (the total energy of the particle) must satisfy

##### 10: 33.22 Particle Scattering and Atomic and Molecular Spectra
With $e$ denoting here the elementary charge, the Coulomb potential between two point particles with charges $Z_{1}e,Z_{2}e$ and masses $m_{1},m_{2}$ separated by a distance $s$ is $V(s)=Z_{1}Z_{2}e^{2}/(4\pi\varepsilon_{0}s)=Z_{1}Z_{2}\alpha\hbar c/s$, where $Z_{j}$ are atomic numbers, $\varepsilon_{0}$ is the electric constant, $\alpha$ is the fine structure constant, and $\hbar$ is the reduced Planck’s constant. … For $Z_{1}Z_{2}=-1$ and $m=m_{e}$, the electron mass, the scaling factors in (33.22.5) reduce to the Bohr radius, $a_{0}=\hbar/(m_{e}c\alpha)$, and to a multiple of the Rydberg constant, … Customary variables are $(\epsilon,r)$ in atomic physics and $(\eta,\rho)$ in atomic and nuclear physics. Both variable sets may be used for attractive and repulsive potentials: the $(\epsilon,r)$ set cannot be used for a zero potential because this would imply $r=0$ for all $s$, and the $(\eta,\rho)$ set cannot be used for zero energy $E$ because this would imply $\rho=0$ always. … The Coulomb solutions of the Schrödinger and Klein–Gordon equations are almost always used in the external region, outside the range of any non-Coulomb forces or couplings. …
