The transverse nuclear magnetic resonance (NMR) decays of $^{129}$Xe inpolycrystalline xenon were recently shown to have a universal property: in thelong-time regime these decays all converge to the same sinusoidally modulatedexponential function irrespective of the initial transverse spin configurationprepared by a sequence of one or more radio frequency pulses. The present workconstitutes a more comprehensive survey of this phenomenon. It examinestransverse decays for several different isotopic concentrations of $^{129}$Xe,employs additional pulse sequences, and performs similar measurements in adifferent material: $^{19}$F in single-crystal and polycrystalline CaF$_2$. Weadditionally verified the polycrystalline nature of our frozen xenon samples byX-ray diffraction measurements. With the possible exception of polycrystallineCaF$_2$ where the observation of the long-time behavior is limited by theexperimental resolution, all these systems display the long-time universalbehavior characterized by particular values of the exponential decaycoefficient and beat frequency that were unique for each lattice. This behaviorhas been theoretically predicted based on the notion of microscopic chaos.
