arc.alkali_atom_functions.AlkaliAtom.getLandegjExact# AlkaliAtom.getLandegjExact(l, j, s=0.5)[source]# Lande g-factor \(g_J=g_L\frac{j(j+1)-s(s+1)+l(l+1)}{2j(j+1)}+g_S\frac{j(j+1)+s(s+1)-l(l+1)}{2j(j+1)}\) Parameters l (float) – orbital angular momentum j (float) – total orbital angular momentum s (float) – optional, total spin angular momentum of state. By default 0.5 for Alkali atoms. Returns Lande g-factor ( \(g_J\)) Return type float
