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
