【 摘 要 】

Double differential cross sections (DDCS) of the secondary electrons emitted from a vapor jet of bromouracil in collision with 42 MeV bare carbon ions have been measured for different forward and backward emission angles over a wide energy range. The DDCS for bromouracil were compared with that of uracil measure earlier. An unusually large increase in electron emission cross section have been observed for bromouracil.
