calculates the radial matrix element.
1 | old_radial_matrix_element(n1, n2, l1, l2, j1, j2, k = 1)
|
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. |
k |
A numeric. The power of r to be calculated over. To get a dipole matrix element, k must be equal to 1. Default k = 1. |
This function calculates the radial matrix element for two arbitrary states (n1, l1, j1) and (n2, l2, j2). A Numerov algorithm is used to compute the radial matrix elements as done in Appendix A of Zimmerman et al, PRA, 20, 2251 (1979). The scaling used in this function is ξ = √ r, Ψ = r^(3/4) R(r) as done by Bhatti, Cromer, and Cooke, PRA, 24, 161 (1981).
