We have observed, for the first time ever, resonant interaction between states responsible for the P-Q and l\~LO luminescence lines. This serves as additional confirmation of the plasma origin of the lines Ρ and Q. The concentration of the electron-hole pairs is estimated at 1.8ΧΙΟ18 cm-3 (P line) and 1.2 X1019 cm-3 (Q line).
