arc.divalent_atom_functions.DivalentAtom.getC3term#
- DivalentAtom.getC3term(n, l, j, n1, l1, j1, n2, l2, j2, s=0.5)#
C3 interaction term for the given two pair-states
- Calculates \(C_3\) intaraction term for
\(|n,l,j,n,l,j\rangle \leftrightarrow |n_1,l_1,j_1,n_2,l_2,j_2\rangle\)
- Parameters
n (int) – principal quantum number
l (int) – orbital angular momentum
j (float) – total angular momentum
n1 (int) – principal quantum number
l1 (int) – orbital angular momentum
j1 (float) – total angular momentum
n2 (int) – principal quantum number
l2 (int) – orbital angular momentum
j2 (float) – total angular momentum
s (float) – optional, total spin angular momentum of state. By default 0.5 for Alkali atoms.
- Returns
\(C_3 = \frac{\langle n,l,j |er |n_1,l_1,j_1\rangle \langle n,l,j |er|n_2,l_2,j_2\rangle}{4\pi\varepsilon_0}\) (\(h\) Hz m \({}^3\)).
- Return type
