ABSTRACT:

Polarized hydrogen and nuclear targets are essential for studying the spin structure and form factors of nucleons. In this work we develop two types of laser-driven polarized gas targets: a low-pressure internal hydrogen (deuterium) target and a high-pressure external helium- 3 target. The targets are polarized through the method of spin-exchange alkali metal optical pumping. This paper describes the target cells, the mechanisms for polarizing the target nucleon and nuclei, the processes for measuring the target's nuclear polarization, and the results of the polarization measurements.
