Lyman gamma profiles perturbed by protons using molecular potential of Peek allow us to identificate a large feature near 995 A in FUSE observations of hot white dwarfs. It is visible also in the HUT spectrum of Wolf1346 and in some ORFEUS spectra. This feature is due to Quasi-molecular Lyman gamma satellites due to H-H+ collisions near 991 and 996A.
