We have investigated the effect of Young type interference on theforward backward angular asymmetry in electron emission from molecularhydrogen in collisions with fast bare carbon ions. The asymmetryparameter shows an oscillatory behaviour as a function of electronvelocity which is absent in atomic target such as He. It is shown thatthe asymmetry parameter which is based on DDCS from H2onlycan be a tool to investigate the Young type interference. The measuredenergy and angular distributions as well as the asymmetry parameter arecompared with a molecular CDW-EIS (continuum distorted wave-eikonalinitial state) model.
