Spin Dependent Superelastic Scattering from Pure Angular Momentum States of Na(3P)

March 31, 1986
Author(s)
Jabez J. McClelland, Michael H. Kelley, Robert Celotta
Spin asymmetries are presented for superelastic scattering of spin-polarized electrons from spin-polarized M L=+1 and M L=-1 states of the Na 3P 3/2 atom. The incident-energy dependence at a scattering angle of 30° is shown for energies of 1.26 to 11.76 eV
