摘要: Photodissociation of N2 has been studied using synchrotron radiation as a light source. The ratio the yield N+ to that N2+ is measured by time-of-flight method pulse characteristics and ratios thus obtained are 7 8.5% at 450, 470 490 AA. Using these curve mass filter, partial cross sections for fragment ion production determined in region from threshold 450 Many peaks due autoionising states converging C 2 Sigma u+ state observed with filter. kinetic energies also several wavelengths electron-ion coincidence method. It suggested analysis energy potential which directly dissociates or predissociates N(4S)+N+(1D)(26.2 eV) crosses Franck-Condon vicinity 471 AA (26.3 eV).
