- AlkaliAtom.getBranchingRatioFStoHFS(jg, fg, mfg, je, mje, s=0.5)[source]#
Branching ratio for decay from \(\vert j_e, m_{j_e} \rangle \rightarrow \vert j_g,f_g,m_{f_g} \rangle\)
- Parameters:
jg (float) – total orbital angular momentum of the lower energy state
fg (float) – hyperfine basis (total atomic) angular momentum of the lower energy state
mfg (float) – projection of the total angular momentum of the lower energy state
je (float) – total orbital angular momentum of the higher energy state
mje (float) – projection of the total orbital angular momentum of the higher energy state
s (float, optional) – total spin angular momentum of the states. By default 0.5 for Alkali atoms.
- Returns:
branching ratio
- Return type:
