SPIN-EXCHANGE OPTICAL-PUMPING AS A SOURCE OF SPIN-POLARIZED ATOMIC DEUTERIUM

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 +/- 3)% at an intensity...

Beschreibung
Zusammenfassung:	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 +/- 3)% at an intensity of 2.1 x 10(17) atoms/s.
