Mean values of powers of the radius for hydrogenic electron orbits
Mean values of powers of the radius for hydrogenic electron orbits is a scholarly work, published in 1974 in ''Physical Review A, General Physics''. The main subjects of the publication include atomic number, electron, zero, physics, integer data type, mathematical physics, quantum mechanics, RADIUS, density functional theory, low-energy electron diffraction, computational chemistry, atomic physics, and degree. The general formulas available in the literature for calculating the time average of powers of the orbital radius of the electron in hydrogenic atoms or ions, $〈{r}^{s}〉$, are of a degree about twice that of the resulting explicit expressions.
