Ailion, David Charles | 93Nb NMR in the imcommensurate and quasi-commensurate phases of barium sodium niobate | NMR spectra have been measured for the quadrupole perturbed 1/2 -1/2 transition of 9 3Nb in barium sodium niobate (BSN) between 300 and 650 K. The spectra are inhomogeneously broadened in the incommensurate (/) phase between T7 = 580 K and r c = 540 K as well as in the quasicommensurate (QC) phase ... | NMR; Spectra; Barium sodium niobate; Line shapes | 1994 |

Ailion, David Charles | Thermal fluctuations and NMR spectra of incommensurate insulators | The effects of thermal order-parameter fluctuations on the NMR line shape of incommensurate systems are evaluated within the mean-field Landau theory and the results are compared with the 8 7Rb and 3 9K 1/2 -1/2 NMR spectra of Rb2ZnCl4 and K2Se04 just below the paraelectric-incommensurate transition... | NMR spectra; Thermal fluctuations; Line shapes; Incommensurate insulators | 1994 |

Morse, Michael David | Spectroscopic analysis of the open 3 d subshell transition metal aluminides: AIV, AICr, and AICo | Three open 3d subshell transition metal aluminides, AlV, AICr, and AlCo, have been investigated by resonant two-photon ionization spectroscopy to elucidate the chemical bonding in these diatomic molecules. The open nature of the 3d subshell results in a vast number of excited electronic states in th... | 1994 | |

Lindstrom, Gary E. | The design of object-oriented meta-architectures for programming languages | This paper is a survey of the design of four object-oriented meta-level architectures for programming languages. We present overviews and compare the salient features of the meta-architectures of Smalltalk, Common Lisp Object System (CLOS), a Scheme Compiler, and Etyma, our framework for modular sy... | Meta-level architectures; Design | 1994 |

Morse, Michael David | Spectroscopy of mixed early-late transition metal diatomics: ScNi, YPd, and ZrCo | Resonant two-photon ionization spectroscopy has been employed to investigate the spectra of the jet-cooled transition metal diatomics ScNi, YPd, and ZrCo, which are isovalent species which possess ~or are thought to possess! an X 2?+ ground state. Several electronic band systems have been observed f... | 1994 |
