# arc.divalent_atom_functions.DivalentAtom.getReducedMatrixElementL#

DivalentAtom.getReducedMatrixElementL(n1, l1, j1, n2, l2, j2, s=0.5)#

Reduced matrix element in $$L$$ basis (symmetric notation)

Parameters
• n1 (int) – principal quantum number of state 1

• l1 (int) – orbital angular momentum of state 1

• j1 (float) – total angular momentum of state 1

• n2 (int) – principal quantum number of state 2

• l2 (int) – orbital angular momentum of state 2

• j2 (float) – total angular momentum of state 2

Returns

reduced dipole matrix element in $$L$$ basis $$\langle l || er || l' \rangle$$ ($$a_0 e$$).

Return type

float
