Abstract
A mass spectrometric method for the determination of the electron work function based on analysis of thermochemical cycles including molecules and ions has been described. Application of this method for calculation of the electron work functions of lanthanum, cerium, and praseodymium triiodides gave 3.8±0.3 eV for LaI3, 3.5±0.3 eV for CeI3, and 2.8±0.3 eV for PrI3.
