Differential Cross Section Measurements for Ionisation of N₂ in Coplanar Geometry
Triple differential cross section measurements for ionisation of N2 are presented in a coplanar geometry where one of the outgoing electrons was fixed in angle. Data were obtained at incident electron energies 20 and 40 eV above the ionisation potential for the 3σg and 1πu states, the outgoing electrons carrying equal energies. Six sets of measurements were obtained at each energy, with fixed angles of 45°, 90° and 125° to the incident electron direction. The data are compared to new calculations using distorted wave methods.
