Mattis, Daniel C. | Bond asymmetry and high-Tc superconductivity | We propose a simple mechanism, anchored in weak-coupling BCS theory, which ties together the following facts: high Tc; quasi two dimensionality; orthorhombic distortion and/or disordered lines of oxygen; proximity to a metal-insulator transition; and anomalously small isotope effects. | Distortion; Singularity; Oxygen | 1987 |

Armentrout, Peter B. | Guided ion beam studies of the reactions of Crn + (n=2-18) with O2: chromium cluster oxide and dioxide bond energies | The kinetic energy dependence of the reactions of Crn+ (n=2-18) with O2 are studied in a guided ion beam mass spectrometer. A variety of CrmO2+, CrmO+, and Crm+ product ions, where m≤n, are observed, with the dioxide cluster ions dominating the products for all larger reactant cluster ions.

Armentrout, Peter B. | Guided ion beam studies of the reactions of Crn+ (n=1-18) with CO2: chromium cluster oxide bond energies | The kinetic energy dependence of the reactions of Crn+ (n=1-18) with CO2 are studied in a guided ion beam mass spectrometer. The primary product ions are CrnO+, which then decompose by sequential loss of chromium atoms as the kinetic energy is increased. Simple collision-induced dissociation to form... | Metal clusters; Chromium ions; Oxygen; Bond energies; Exothermic reactions; Endothermic reactions | 1998 |

Armentrout, Peter B. | Kinetic energy dependence of Al+ + O2→AlO+ + O | The endothermic reaction of Al+ with O2 is studied using a guided ion-beam apparatus. The reaction cross section is measured as a function of kinetic energy from 0 to 20 eV. The threshold energy for the reaction, E0, is determined from an empirical model to be 3.64 ± 0.04 eV. | Ion-molecule reactions; Translational energy; Threshold behavior; Endothermic reactions; Aluminum; Oxygen | 1986 |

Armentrout, Peter B. | Translational energy dependence of O+(4S) + N2 → NO+ + N from thermal energies to 30 eV c.m. | Guided ion beam mass spectrometry is used to examine the kinetic energy dependence of the reaction of ground state atomic oxygen ion with molecular nitrogen. An 0 + (4S) source which produces less than 0.06% excited states is described. Cross sections for the NO+ + N product channel decrease with... | Ion-molecule reactions; Translational energy; Threshold behavior; Endothermic reactions; Nitrogen; Oxygen | 1987 |
