Abstract

The angular distribution of electrons elastically scattered from ${\mathrm{N}}_{2}$ as a function of energy has been measured utilizing a crossed-beam technique. Measurements have been made of monoenergetic electrons with energies between 5 and 90 eV scattered from a collimated beam of ${\mathrm{N}}_{2}$ at angles from - 114\ifmmode^\circ\else\textdegree\fi{} to + 160\ifmmode^\circ\else\textdegree\fi{}. The wide angular range of the measurements has enabled the determination of the total elastic-scattering and momentum-transfer cross sections. The measurements are relative and have been normalized to Fisk's theoretical calculation at 5 eV. The results generally agree well with other published measurements and with theory.
