Popis: Photoionization efficiencies for the various fragments of 1.1-difluuoroethane (Freon 152 A) as well as the threshold photoelectron spectrum at photon energies between 10 and 20 eV have been measured. The appearance energy of the parent ion AP = 11.865 eV and Δ 1 H 2?? o = 644.0±6 kJ/mol. A number of excess-energy corrections for fragmentation reactions have been obtained and the decomposition of the CH 3 CHF 2 + ion is documented with energy derivatives of the photoionization efficiencies and a breakdown diagram. At photon energies above 16 eV isolated-state behaviour was detected.
