【 摘 要 】

Ion impact induced fragmentation of H2O molecules was experimentally studied. Energy and angular distribution of the charged fragments were measured by an energy dispersive electrostatic spectrometer. The measured spectra were converted into absolute double differential cross section (DDCS). The fragment ion spectra are different for H+and N+projectiles. From the fragmentation spectra we deduced the cross sections for the different ionization degrees of the target molecules.
