Distribution of NQR relaxation times in the rotating frame of reference in micro-sized crystallites
This article presents the results of an experimental study into the effect of powder crystallite size on spin-lattice relaxation times in a rotating frame for 35Cl NQR in potassium chlorate, as well as the nutation interferograms. To obtain the distribution of relaxation times, a multi-exponential decay inversion of the longitudinal component of the nuclear magnetization in a rotating frame was used. The multimodal nature of distributions is explained by ...
Geometrical phase of NQR signals
... expressions for the geometric phases of NQR signals were obtained for the case of nuclei with spin I = 3/2. The powder sample of KClO3 was served as a material for experimental part of studies reported. It was proposed an alternative variant of the nutation experiment, which allows one to obtain the asymmetry parameter η on the base of locations of frequency singularities in the nutation phase spectrum.
