arc.alkali_atom_functions.AlkaliAtom.potential

AlkaliAtom.potential(l, s, j, r)

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
