Elastic electron scattering in krypton in the energy range from 5 to 10 eV

Abstract

Differential cross sections for elastic electron scattering in krypton have been measured at the energies of $5,7.5$, and $10$ eV over the scattering angle range from ${30}^{\ifmmode^\circ\else\textdegree\fi{}}$ to ${180}^{\ifmmode^\circ\else\textdegree\fi{}}$. The measurements for backward scattering employed the magnetic angle-changing technique. These differential cross sections have been integrated to yield the elastic integral and momentum transfer cross sections at the above energies. These new results are compared with the most recent measurements and calculations of the respective cross sections in krypton. The dependence of the differential cross sections on atomic polarizability of the heavier rare gas atoms argon, krypton, and xenon has also been investigated over the electron energy range $5--30$ eV and for forward, backward, and intermediate scattering angles.
