Fig. (9) The dependence of specific power losses on the electron collision in a mixture of mercury dibromide and mercury diiodide vapor with helium on the reduced electric field strength (E/N): 1 - dissociative excitation of the В²Σ⁺_1/2-state of HgI* molecules, 2 - dissociative excitation of В²Σ⁺_1/2-state of HgBr* molecules, 3 - dissociative excitation of the Х²Σ⁺_1/2-state of HgBr* molecules, 4- excitation of the electronic state of mercury dibromide (HgBr₂ (D)).
