摘要：
The yields of positive ionic fragments produced by positron impact from CH3Cl have been studied in the energy range from threshold to 50 eV. The interactions take place whilst the positrons are stored in a Penning trap and the ions are detected using a rime of flight mass spectrometer. The cross-sections for production of the parent molecular ion and the fragment CH3+ are presented. (C) 1999 Elsevier Science B.V. All rights reserved.
