It is equal to approximately 2, 2/3, and 4/3 for the D-lines of sodium.
The effect of lateral confinement on this quantity on the holes in gallium arsenide semiconductors was reported in 2006. In 1925, it was while working as an assistant to its German-American namesake that Ralph Kronig hypothesized spin. For a given amount of total angular momentum, it may be quantified as the energy change divided by the product of magnetic quantum number, nuclear magneton, and nuclear magnetic field. It is equal to approximately 2, 2/3, and 4/3 for the D-lines of sodium. For the electron, it is approximately 2 and is one of the most precisely-measured quantities in physics. FTP, what is this dimensionless unit, the ratio of the magnetic dipole moment to the angular momentum, which is a quantification of the interactions that generate the Zeeman Effect?
