 | Ailion, David Charles | 14N study of the role of N-D---O bonds in the deuteron glass transition | 14N spin-lattice relaxation-time measurements in Rb0.28(ND4)0.72D2PO4 provide direct evidence for the fast exchange averaging of the "long" and "short" N-D---O hydrogen bonds between the ND4 group and the four surrounding PO4 groups. This exchange and the associated distortion of the ND4 tetrahedron... | NMR; Hydrogen bonds; Spin-lattice; Relaxation-time; Deuteron glass | 1999 |

 | Ailion, David Charles | 31P NMR spin-lattice relaxation: structural glass dynamics in Rb1-x(ND4)xD2PO4 | We performed 3 1P NMR measurements of the temperature-dependent spin-lattice relaxation time in several mixed single crystals of Rbi_x(ND4 ) xD2P04 [DRADP] having different ammonium concentration x (x =0.22, 0.44, 0.78) as well as in three pure single crystals (ND4)D2P04 [DADP], (NH4)H2P04 [ADP], an... | NMR; Spin-lattice; Relaxation; Crystals; Glass; Spin-glass | 1993 |

 | Ailion, David Charles | 79Br nuclear-quadrupole-resonance lineshape and Raman-induced spin-lattice relaxation in the incommensurate phase of β- ThBr4 | We performed 7 9Br nuclear-quadrupole-resonance (NQR) line-shape and spin-lattice relaxation time measurements in the incommensurate (D system j8-ThBr4 over the temperature range 293-2.5 K. In addition, we extended the theory of the effects of Raman processes on amplitudon and phason spin-lattice re... | Spin-lattice; NQR; Raman process; Line shape; Phason gap; Incommensurate systems | 1989 |

 | Ailion, David Charles | Dynamics of the pinned modulation wave in incommensurate bis (4-chlorophenyl) sulfone (BCPS) | We show that both the anomalously huge resonance-frequency dependence of the 3 5Cl nuclear quadrupole resonance (NQR) spin-lattice relaxation time in BCPS, reported here for the first time, and its anomalous temperature dependence can be explained by large-scale fluctuations of the pinned modulation... | NQR; Spin-lattice; Relaxation-time; Pinned modulation wave | 2002 |

 | Ailion, David Charles | Gallium and thallium NMR study of phase transitions and incomemensurability in the layered semiconductor TlGaSe2 | We report on the first NMR study of phase transitions and incommensurability in the layered semiconductor TlGaSe2. 69,71Ga and 205Tl NMR data from a powder sample show phase transitions at 118, 108 and around 69 K. The 69Ga and 71Ga spin-lattice relaxation times T1 are short and nearly temperature i... | NMR; Atomic motion; Phase transitions; Spin-lattice; Relaxation-time | 2004 |

 | Ailion, David Charles | NMR in substitutionally disordered incommensurate (Rb1-xKx)2ZnCl4 | The impurity-concentration dependence of the 8 7Rb NMR line shapes and phason-induced spin-lattice relaxation rates has been studied over a wide temperature range in substitutional^ disordered incommensurate (Rb1_xKJ C)2ZnCl4 for x =0.00, 0.02, and 0.06. The results yield information on the impurity... | NMR; Line shapes; Phasons; Spin-lattice; Phase fluctuations | 1994 |
