摘要：

The fragmentation patterns of the halomethanes CCl2F2, CClF3, CF4, and CHF3 have been studied by positron impact, in the energy range from threshold to around 50 eV. These data were obtained using a quadratic potential time of flight mass spectrometer, coupled with a Penning trap and a LINAC-based positron source. The present data for positrons are compared with results for-electron and photoionization from other works.
