AlkaliAtom.getEnergyDefect(n, l, j, n1, l1, j1, n2, l2, j2, s=0.5)[source]#

Energy defect for the given two pair-states (one of the state has two atoms in the same state)

Energy difference between the states \(E(n_1,l_1,j_1,n_2,l_2,j_2) - E(n,l,j,n,l,j)\)

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. Spin angular momentum (default 0.5 for Alkali)

Returns:

energy defect (SI units: J)

Return type:

float
