Spin Dependent Superelastic Scattering from Pure Angular Momentum States of Na(3P)
Jabez J. McClelland, Michael H. Kelley, Robert Celotta
Spin asymmetries are presented for superelastic scattering of spin-polarized electrons from spin-polarized ML=+1 and ML=-1 states of the Na 3P3/2 atom. The incident-energy dependence at a scattering angle of 30° is shown for energies of 1.26 to 11.76 eV. In addition, angular dependences over the range 5° to 40° are given at 2.0 and 9.26 eV. Large differences are seen between the spin asymmetries for the two ML sublevels of the excited state, with the ML=-1 asymmetry reaching a value of 100% at 2 eV and 35° scattering angle, corresponding to pure singlet scattering.
