I'm looking for the general formula for Angular Momentum radiated away from quadrupolar electromagnetic radiation. I searched the usual books (Jackson, Landau-Lifchitz, ...) and just found the usual dipolar contributions.
Using dimensional analysis and energy radiated away, I found this formula, but I need a confirmation that it's the right one.
[itex]\frac{dL_i}{dt} = - \frac{1}{90} \, \frac{1}{4 \pi \epsilon_0 c^5} \, \varepsilon_{ijk} \; \ddot{Q}_{jl} \; \dddot{Q}_{lk}.[/itex]
Someone has a comment on this ? Any reference ?
