The recent past has shown a significant progress in the spin exchange optical pumping technology. Spin-exchange optical pumping is a process whereby photon angular momentum is transferred to target nuclei through spin-exchange collisions with polarized alkali-metal atoms. In spite of their small numbers, alkali-metal atoms could significantly dilute the nucleon polarization in the target, because of there are a large number of unpolarized nucleons in the alkali nuclei. Also, if potassium atoms are used in the pumping cell with a density of one percent of the hydrogen density, the losses of the high energy electrons in the storage ring due to the presence of potassium is two time higher than the losses due to the hydrogen.
