Hello everyone, What we can call those GW+BSE (e-h interaction) peaks, which appear after the optical band gap?

Fig. attached show the imaginary part of bulk system with GW and GW+BSE calculation. Present optical gap (GW) is 1.38 eV. Can we call these peaks (P1, P2, P3 appear at 1.45, 1.65 and 1.98 eV,...
