to calculate the energy spectrum of the electron bound states.
From these calculations it follows that the electron energy is
quantized, and these energies are given by the expression:
where n is the principal quantum number of the atomic
level, and
is a fundamental physical constant called the Rydberg
constant (here me is the electron mass). Numerically,
Ry = 1.0974 × 105
cm−1 and hcRy = 13.605eV.
Because the allowed energies of an electron in a hydro
