Dynamic nuclear polarization of irradiated targets

The authors have irradiated and studied dynamic nuclear polarization in ammonia, deuterated ammonia, butanol borane ammonia, methylamine, ethane and lithium borohydride in order to test these substances for potential use as polarized target materials. These studies were conducted using a polarized target system operating at a temperature of 1K and a magnetic field of 5T. The target system was set up in a beam line at the Stanford Linear Accelerator Center, enabling them to irradiate the targets in situ at 1K with a 6 to 20 GeV electron beam and to study their polarization property simultaneously. 7 references, 6 figures
