Popis:	Molecular and ionic sublimation of gadolinium and terbium tribromides in Knudsen and Langmuire modes was studied by the method of high-temperature mass-spectrometry. On the basis of obtained enthalpies of sublimation and ion-molecule reactions the enthalpies of formation of LnBr3 and Ln2Br6 molecules and LnBr4− and Ln2Br7− negative ions were determined. For the first time the electron work function for crystals of the studied tribromides was calculated.
