DivalentAtom.getReducedMatrixElementJ(n1: int, l1: int, j1: float, n2: int, l2: int, j2: float, s: float = 0.5) → float#

Reduced matrix element in \(J\) 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

  • s (float) – optional, total spin angular momentum of state. By default 0.5 for Alkali atoms.

Returns:

reduced dipole matrix element in \(J\) basis \(\langle j || er || j' \rangle\) (\(a_0 e\)).

Return type:

float
