principal quantum number

[′prin·sə·pəl ′kwän·təm ‚nəm·bər]
(atomic physics)
A quantum number for orbital electrons, which, together with the orbital angular momentum and spin quantum numbers, labels the electron wave function; the energy level and the average distance of an electron from the nucleus depend mainly upon this quantum number.

Using different approximations, considerable efforts have been made for calculating these integrals over STOs with noninteger principal quantum numbers n (NISTOs).
The obtained formula is basic and valid for arbitrary integer and noninteger principal quantum numbers.
It is also observed that the energy E increases monotonically with the magnetic field parameter B, and for one principal quantum number, the energy E increases with the increase of the azimuthal quantum number.
