Miller, Joel Steven; Epstein, Arthur J. | Evidence for solitons in conducting organic charge-transfer crystals | Magnetic susceptibility of (N-methylphenazinium)x(phenazine)(1-x (tetracyanoquinodimethanide) [(NMP)x(Phen)1-x(TCNQ)] shows the formation of defect states for 0.5<x<0.54. Diffuse x-ray scattering and g-value studies indicate that these defects are solitons formed in the highly correlated quasi-one-... | TCNQ; X-ray scattering | 1982 |

Miller, Joel Steven; Epstein, Arthur J. | Optical properties of the cation-deficient platinum chain salt K1.75Pt(CN)4¢1.5H2O | The room-temperature polarized reflectance of a potassium-deficient platinum chain salt K1.75Pt(CN)4.1.5Hz[K0 (def)CP] has been measured in the infrared and visible. The reflectance is strongly anisotropic, with a plasma edge in the red and high reflectance in the infrared for light polarized para... | Reflectance; Crystals; Lattice | 1982 |

Armentrout, Peter B. | Reaction of Cr+, Mn+, Fe+, Co+, and Ni+ with O2 and N2O. Examination of the translational energy dependence of the cross sections of endothermic reactions | Reactions of Cr+, Mn+, Fe+, Co+, and Ni+ with 02 and N20 to yield metal oxide ions are examined using an ion beam apparatus. Reaction cross sections a as a function of ion translational energy E are reported. With one exception, Fe+ + N20, the cross sections exhibit an energy threshold E0. | Metal oxides; Endothermic reactions; Translational energy; Bond energy; Threshold energy | 1982 |

Miller, Joel Steven; Epstein, Arthur J. | X-ray observation of crossover of 2kF to 4kF scattering in (N-Methylphenazinium)x(Phenazine)1-x(Tetracyanoquinodimethane) [(NMP)x(Phen)1-x(TCNQ)], 0.5 (< _x <_ 1.0) | We report the temperature-dependent x-ray diffuse scattering of (NMP),(Phen)(1-x-)(TCNQ) as a function of conduction-electron density (x). With decreasing x three different unique electronic instability regimes are successively observed on the TCNQ chains: (i) the 2kF instability for (2/3<_x<_1, (ii... | Conduction-electron; Electron density; Chain | 1982 |
