Spectral line shape and angular momentum

Data have been obtained for ejection of valence shell 4p and 3d electrons in krypton and the 1t2 and 2a1 orbitals in methane. Measurements, with kinematics both on and off the Bethe ridge, examine how the spectral shapes change for fixed energies of 1015 eV for the incident electron, 880 eV for scat...

Summary:Data have been obtained for ejection of valence shell 4p and 3d electrons in krypton and the 1t2 and 2a1 orbitals in methane. Measurements, with kinematics both on and off the Bethe ridge, examine how the spectral shapes change for fixed energies of 1015 eV for the incident electron, 880 eV for scattered and 120 eV for ejected electron and angular momentum changes. The studied interactions are activated by excitation and ionization of inner shell (-d) electrons and concern complex electron correlations. The triple differential cross sections for the Bethe ridge conditions within the experimental accuracy are similar to the values predicted by the Distorted Wave Impulse Approximation and Born Approximation calculations but need further consideration of electron correlation effects.
