A Method to Measure Positron Beam Polarization Using Optically Polarized Atoms
Atoms, 2023 We outline an experimental technique for measuring the degree of polarization of a positron beam using an optically pumped, spin-polarized Rb target. The technique is based on the production and measurement of the ortho- and para-positronium fractions ...
