calculates the elements of a Stark matrix
1 | stark_matrix_elem(n1, n2, l1, l2, j1, j2, mj1, mj2)
|
n1 |
A numeric. The principle quantum number of state 1. |
n2 |
A numeric. The principle quantum number of state 2. |
l1 |
A numeric. The orbital angular momentum number of state 1. |
l2 |
A numeric. The orbital angular momentum number of state 2. |
j1 |
A numeric. The total angular momentum number of state 1. |
j2 |
A numeric. The total angular momentum number of state 2. |
mj1 |
A numeric. The magnetic angular momentum number of state 1. |
mj2 |
A numeric. The magnetic angular momentum number of state 2. |
This function calculates contribution to the energy due to the Stark effect for an arbitrary set of states (n1, l1, j1, mj1) and (n2, l2, j2, mj2). The element is determined based on equation 10 from Zimmerman et al., PRA, 20, 2251 (1979). For a non-zero matrix element, the conditions mj1 = mj2 and l2 = l1 +/- 1 must be met.
