Studies of electron exchange collisions and polarized electron production in a flowing helium afterglow
A flowing helium afterglow apparatus has been used to study thermal-energy electron exchange collisions between spin-polarized electrons and O$\sb2$ or NO molecules. Penning ionization of CO$\sb2$ by spin-polarized ...
Energy dependent electron polarization studies of penning ionization channels
Penning ionization reactions have been studied in a flowing afterglow apparatus to explore the contributions of autoionizing channels in reactions of spin-polarized He(23S) with alkali atoms. Spin polarization analysis of ...
