Figure 24.

(a) real-space plot of the electric field modulus concerning to a calculated quasibound state at $nk{r}_0\approx 200$ with an eccentricity deformation ($ϵ=0.10$); (b) angular momenta distribution for the resonance plotted in (a). The peak at negative m corresponds to clockwise rotation, and the weak peak at positive m corresponds to counterclockwise rotation; the counterclockwise modes are the diffracted waves emitting from the notch.
