Abstract
Dynamic deuteron polarization has been demonstrated in deuterated ammonia, using paramagnetic radicals created by electron irradiation. During the irradiation, performed in the 20 MeV electron beam of the Bonn injection linac, the solid ammonia beads were cooled in liquid argon at a temperature of 87 K. A deuteron polarization of 11% was obtained in a field of 2.5 T and at a temperature of 0.5 K. These first measurements with an irradiated ND3 sample indicated a rather small electron spin resonance line. The deuteron tensor polarization could be changed by a simple method.
