We study the CN- production from cyanogen using an experimental setup which combines the trochoidal electron monochromator with the velocity map imaging detection spectrometer. The setup is quantitative and the absolute dissociative electron attachment cross sections are determined using the relative flow technique. The peak value of the dissociative electron attachment cross section is 0.16 Å2 at 5.2 eV. The angular distribution of fragments changes its character considerably with varying electron energies and reveals different symmetries of the involved resonant states.
