“…The asymmetric/~ radiation was used in the cases of aLi [1], 2~ [2,3], 116In [4], 11~ [5], 28A1 [6], and 3~C1 [6] as a tool to detect nuclear magnetic resonance (NMR) signals from which nuclear moments were determined. Some of these isotopes have been investigated repeatedly [7 -9] in order to determine NMR line shapes as a function of radio frequency (rf) power, temperature and crystal orientation.…”

Polarized 11~ nuclei are produced in the silver halides by capture of polarized neutrons at temperatures below 30 K and magnetic field strengths up to 6 kOe. The depolarization process is studied by observation of the 11 decay asymmetry as a function of magnetic field, temperature and of the radio frequency field strength in NMR signals. The depolarization is caused by a field dependent deorientation process and by temperature dependent spin-lattice relaxation. The deorientation is due to a succession of coupling steps of the nuclear spin with electromagnetic fields of defects generated as a consequence of the capture process, and the field dependence of the polarization can be understood as a decoupling curve. The temperature dependence of the spin-lattice relaxation is in accordance with the theory of quadrupolar relaxation above 18 K if an empirical phonon spectrum is used for the calculation. At lower temperatures the experimental relaxation rate is anomalously high, which may be due to resonance modes connected with recoil lattice defects.
