Absolute Differential Cross Sections of Elastically Scattered Electrons. III CO and N2 at 500, 400, and 300 eV

Absolute differential cross sections of electrons elastically scattered by CO and N2 have been measured at 500, 400, and 300 eV. At scattering angles greater than 12° there is no significant difference between the two isoelectronic molecules. At small angles the cross sections for CO increase at a slightly faster rate than for N2, reflecting the presence of a dipole moment for the heteronuclear CO molecule.
