Abstract

A simple development of the PEPIPICO technique, utilising the continuum nature of synchrotron radiation, has been used to determine thresholds for fragmentation of NH3 into the channels NH+2+H+ (35.7 and 39.6 eV), NH++H+ and NH++H+2 (43.3 eV) and N++H+ (49.2 eV). The threshold of NH2+3 metastable ion production has also been determined (33.7 eV).
