摘要：

The dependence on the gas pressure of translational energy losses, DELTA-E, suffered by incident ions in collision with helium target gas atoms was investigated for the [M + Na] + ion of valinomycin. DELTA-E was measured from the fragment ion peak positions in the mass-analysed ion kinetic energy (MIKE) spectra. The variation of DELTA-E with target gas pressure was found to be different for different fragment ions. The implications of the results for the number of collisions which may occur under normal collision-induced decomposition conditions (30-40% transmission) are discussed.
