A study of resonance structures in elastic electron scattering from helium, neon, argon, krypton and xenon over the angular range from 100 to 180

Abstract

Resonance structures corresponding to the 2sS state in He and the np(n + 1) s(S) states in Ne, Ar, Kr and Xe have been studied in elastic electron scattering over the angular range from 100 to 180. A newly developed magnetic angle-changing technique has been used and this has allowed the first observation of these structures at and near to 180. The widths and energies of the resonance states in krypton and xenon have been determined.
