Fragmentation of hydrocarbons by collision. AGAT@ANDROMEDE.

Abstract

Synopsis We are studying small hydrocarbons produced in high velocity (3.4 a.u.) collision between CH y + cations and He atoms. During the collision those hydrocarbons gain some energy and release this energy doing fragmentation. Thanks to the detector AGAT we have been able to measure fragmentation branching ratios for CH y q + (y=2-4, q=0-3). We also constructed semi-empirical breakdown curves for CH y q + using these experimental branching ratios.
