AlkaliAtom.effectiveCharge(l: int, r: float) → float

effective charge of the core felt by valence electron

For more details about derivation of model potential see Ref. [#marinescu]_.

Parameters:

• l (int) – orbital angular momentum

• r (float) – distance from the nucleus (in a.u.)

Returns:

effective charge (in a.u.)

Return type:

float
