Preliminary report on the photoionization efficiency spectrum, ionization energy and heat of formation of Br(sub 2)O; and the appearance energy of BrO(sup +) (Br(sub 2)O)

摘要

We report experimental results for the photoionization efficiency (PIE) spectrum of Br(sub 2)O along with the ionization energy (derived form the ionization threshold) and the appearance energy (AE) of BrO(sup +) (Br(sub 2)O). A value for the heat of formation of Br(sub 2)O is derived form the AE result. Experiments were performed by employing a discharge flow-photoionization mass spectrometer (DF-PIMS) apparatus coupled to beamline U-11 at the National Synchrotron Light Source (NSLS) at Brookhaven National Laboratory.
