【 摘 要 】

Fragmentation of thymine in the gas phase is 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 the ionization threshold to 400 eV, and excitation functions of most of the positively charged fragments have been extracted.
