The experiment was carried out at the Low Energy Ion Beam Facility (LEIBF) of Inter-University Acceler- ator Centre (IUAC), New Delhi, India. Xe 3+ projectile ions with 810 keV energy (velocity = 0.5 a.u.) were made to interact with molecules of neutral 1,3-butadiene in an evacuated chamber under single collision conditions. The ion-molecule interaction was studied using a recoil ion momentum spectrometer equipped with a position sensitive micro-channel plate (MCP) detector and a channel electron multiplier (CEM). The ions and electrons generated during the interaction are extracted using an electric field of 400 V/cm. The time-of-flight of the recoil fragments was recoded in coincidence with an emitted electron. Using a multi-hit time-to-digital convertor, all recoil fragments corresponding to a single start trigger were collected in coincidence.
