Effects of adsorbates and temperature on electron spin polarization in low energy electron diffraction from tungsten (001)
The electron spin polarization and intensity of the specularly reflected () low energy electron diffraction (LEED) beam at an angle of incidence = 13° have been measured as a function of up to about 1 Langmuir of exposure ...
Spin dependence of penning ionization and production of polarized electrons in a flowing helium afterglow
This dissertation describes a method to study the dependence upon electron spin orientation of ionizing (Penning) reactions of the type He(23 Sl) + X ---> He(11S0) + X+ + e- Helium metastable 23S1 atoms are spin polarized ...
