The novel properties of He (2.3S) metastable atoms will                    form the theme of this research program.  Electron spin                         labelling techniques will be used to explore the dynamics of                    Penning ionization reactions involving He(2.3S) atoms in an                     optically pumped flowing helium afterglow apparatus, which will                 also be used to investigate spin exchange in collisions between                 polarized electrons and open shell targets such as 0.2.  The                    performance of the flowing helium afterglow as a source of                      polarized electrons will also be investigated utilizing newly                   developed lasers to optically orient the He(2.3S) electron                      spins.  Conservation of spin angular momentum in He(2.3S).                      Penning reactions with closed shell partners will be exploited                  in a crossed beam apparatus to provide a new technique for                      absolute calibration of electron spin polarimeters.  The                        interactions of He(2.3S) atoms at a liquid helium surface will                  be investigated, with expectation that the He(2.3S) atoms will                  be trapped there.  Attempts will be made to modify these                        interactions by spin polarizing the He(2.3S) atoms.
