Annotatsiya
Optical pumping of potassium atoms followed by spin-exchange scattering with deuterium atoms in a high magnetic field was found to produce an intense, highly spin-polarized beam of atomic deuterium. In particular, the atomic polarization of deuterium was determined to be (73\ifmmode\pm\else\textpm\fi{}3)% at an intensity of 2.1\ifmmode\times\else\texttimes\fi{}${10}^{17}$ atoms/s.
