Large Angle Superelastic Electron Scattering from Na(3P)
Jabez J. McClelland, Michael H. Kelley, Robert Celotta
Measurements of superelastic scattering of 2eV electrons from oriented Na(3P) atoms have been carried out over the angular range 10 to 120°. Results are presented in terms of Lperp}, the angular momentum transferred perpendicular to the scattering plane. Comparison is made with previous experiments at small angles, and with close-coupling calculations. Good agreement is seen with earlier experimental work, but significant disagreement is seen with theory at angles beyond 40°.
