Description Usage Arguments Details
sphere_mat_element
calculates the spherical matrix element
1 | sphere_mat_element(l, lprime, ml)
|
l |
A numeric. The orbital angular momentum of the starting state. |
lprime |
A numeric. The orbital angular momentum of the final state. |
ml |
A numeric. The magnetic momentum of both the starting and final state. The m_l of each state must be equal. |
This function calculates the spherical matrix element for a given l, l', and m_l. It finds the matrix element <l, m|cos(theta)|l', m> based on a paper by Zimmerman et al, PRA 20, 2251 (1979).
