Spin asymmetries are presented for superelastic scattering of spin-polarized electrons from spin-polarized M/sub L/ = +1 and M/sub L/ = -1 states of the Na 3P/sub 3/2/ atom. The incident energy dependence at a scattering angle of 30/sup 0/ is shown for energies of 1.26 to 11.76 eV. In addition, angular dependences over the range 5/sup 0/ to 40/sup 0/ are given at 2.0 and 9.26 eV. Large differences are seen between the spin asymmetries for the two M/sub L/ sublevels of the excited state, with the M/sub L/ = -1 asymmetry reaching a value of 100% at 2 eV and 35/sup 0/ scattering angle, corresponding to pure singlet scattering.
