Radiation chemistry of acetylene at high intensity: the initial product distributions

The distribution of products observed in the radiation chemistry of acetylene at high dose rate is dramatically different from that observed at low dose rate. The dominant products observed at high dose rate are vinyl acetylene and diacetylene with C3 to C9 compounds having smaller but significant yields. At low dose rate benzene and cuprene are the exclusive products. The difference in product distribution is attributed to the suppression of secondary attack on products at high dose rate so that the observed distribution approximates more closely the 'zero dose' or 'initial' distribution.
