· Journal of Chemical Physics
Utilizing a recently developed method, the ratios of elastic differential cross sections (DCS) of N$sub 2$ to those of He have been measured at electron impact energies of 5, 7, 10, 15, 20, 30, 40, 50, 60 and 75 eV covering an angular range of 20degree to 135degree at each energy. The absolute values of N$sub 2$ DCS (which, in the present work, also include the DCS for pure rotational excitation) have been obtained from these ratios by the use of absolute He DCS of McConkey and Preston. From the differential cross sections, elastic integral and momentum transfer cross sections have been evaluated. The results of the present experiment are compared with some previous measurements.
