title = "Dynamic nuclear polarization of irradiated targets",
abstract = "We report studies of dynamic nuclear polarization of irradiated targets. The polarized target operated at a magnetic field of 5 T and a temperature of 1 K and was irradiated with the 20 GeV electron beam at the Stanford Linear Accelerator. Our results indicate that the temperature at which the target is irradiated is important. The maximum proton polarization attained with radiation was measured for some seven hydrogen-rich compounds. Irradiated NH3 and ND3 were polarized to high values of Pp {reversed tilde equals} 0.75 and Pd {reversed tilde equals} 0.25 with short values of polarization growth time Tp, and with radiation resistance of the polarization about a factor of 30 greater than for normal chemically-doped hydrocarbons. Hence, irradiated NH3 and ND3 appear very promising as practical polarized target materials.",
