【 摘 要 】

Fragmentation of uracil in the gas phase has been studied using low-energy electron impact. Positive ions have been detected using a reflectron time-of-flight mass spectrometer. Mass spectra have been measured as a function of electron impact from 0 to 100 eV, and ion yield curves most of the positively charged fragments have been extracted.
