arc.alkali_atom_functions.AlkaliAtom.potential# AlkaliAtom.potential(l, s, j, r)[source]# returns total potential that electron feels Total potential = core potential + Spin-Orbit interaction Parameters l (int) – orbital angular momentum s (float) – spin angular momentum j (float) – total angular momentum r (float) – distance from the nucleus (in a.u.) Returns potential (in a.u.) Return type float
