Nuclear spin-polarized HD, D/sub 2/, HT and DT solids, liquids and high density gases. Quarterly status report No. 5, March 1, 1985-May 31, 1985
Success is reported in attaining extremely pure o-D/sub 2/ in the 0.997-0.999 range by symmetry species conversion at a temperature of 4K on a partially activated charcoal catalyst. Spin-lattice relaxation times have been improved to over 1 minute. Long storage times and the possibility of liquefication without depolarizing the o-D/sub 2/ are expected. Super-pure o-D/sub 2/ may also be used to probe magnetic impurities on surfaces. In addition, 50 kV ''white spectrum'' x-ray irradiated solid D/sub 2/ experiments have yielded information on defect generation rates and defect lifetimes, as well as their effect on para-ortho D/sub 2/ conversion. Experiments have also been begun in epitaxial deposition of D/sub 2/ on HD, and HD on mostly p-H/sub 2/. Tests of a dilution refrigerator have been completed. (LEW)
