Mattis, Daniel C. | Band theory of ferromagnetism, antiferromagnetism, and spin waves | Intra-atomic exchange (Hund's rule mechanism) and Heisenberg nearest-neighbor exchange are examined for their role in the ferromagnetism of metals with degenerate bands. The equations of motion of spin waves valid near T=0°K are derived, and a number of branches are found. When the equations are ... | Orbital degeneracy; Indirect exchange theory; Band theory | 1964 |

Mattis, Daniel C. | Long-ranged magnetic polarization effects | Two years ago a group1 at Bell Telephone Laboratories discovered an exceedingly long-ranged magnetic interaction among rare earth (RE) atoms dissolved in palladium. It is the purpose of the present note to suggest a theory for this phenomenon, which, it will be recalled, could not be explained by t... | Indirect exchange theory | 1964-05 |

Miller, Jan D. | Metal ion activation in xanthate flotation of quartz | Quartz cannot be floated with potassium amyl xanthate as collector at any pH. Complete flotation is achieved with certain minimal additions of amyl xanthate and Pbtt from pH 5.8 to 8.5 and with amyl xanthate and Znt+ from pH 7.5 to 8.1. The active species of these metal ions responsible for activ... | pH (Chemistry); Xanthate flotation; Metal ions | 1965 |

Ailion, David Charles | Observation of ultraslow translational diffusion in metallic lithium by magnetic resonance | The theory of a new magnetic-resonance technique for studying the ultra slow motion of atoms was presented in a previous paper. In this paper, we present its experimental confirmation for the case of translational diffusion in lithium metal. By this technique the mean time between atomic jumps r can... | Ultraslow atomic motion; Magnetic resonance | 1965 |

Miller, Jan D. | Chrysocolla flotation by the formation of insoluble surface chelates | Pure chrysocolla is floated with chelating agents that form insoluble complexes with copper at ambient temperature. Complete flotation is obtained with potassium octyl hydroxamate as collector at pH 6. Flotation response is enhanced with increased temperature when low additions of h ydroxamate are ... | Chrysocolla; Copper chelating compounds; Flotation systems | 1965 |

Mattis, Daniel C. | Exact solution of a many-fermion system and its associated boson field | Luttinger's exactly soluble model of a one-dimensional many-fermion system is discussed. We show that he did not solve his model properly because of the paradoxical fact that the density operator commutators [p(p), p(-p')], which always vanish for any finite number of particles, no longer vanish in ... | Many-electron problem; Fermi surface; Boson field; Dirac sea | 1965 |

Mattis, Daniel C. | Localized magnetic moments in dilute metallic alloys: correlation effects | We discuss qualitatively the importance of the correlation energy in determining the ground state of a metal with an impurity atom. For a single, partly occupied impurity Estate orbital, the correlation energy acts to prevent the appearance of a nonvanishing ground-state spin, so that this simple no... | Magnetic moments; Metallic alloys; Correlation energy; Magnetic impurities; Orbital degeneracy | 1965-11 |

Dawkins, Beverly Ann | The embryonic development of the California Gull | The California gull (Larus califomicus) is a summer resident in Utah nesting commonly on certain islands in Great Salt Lake as well as at man-made refuges on the east side of the lake. Many aspects of the biology of the species have been investigated (Beck, 1942; Behle, 1958; Behle and Goates, 1957;... | 1965-12-03 | |

Flynn, John J. | Constitutional difficulties of Utah's executive branch and the need for reform | Utah's constitution of 1896 has been aptly described as a "horse and buggy" constitution. Like most of her sister states, Utah adopted a constitution designed to accommodate a society accustomed to the nineteenth century pace of a horse and buggy at the very time that the industrial revolution was l... | Utah, Constitution; Executive branch | 1966 |

Mattis, Daniel C. | Theory of paramagnetic impurities in semiconductors | In this paper, a model of a paramagnetic impurity in a semiconductor (or of an F' center in an alkali halide) is proposed. It is an exactly soluble form of the quantum-mechanical 3-body problem. Specifically, we deal with 2 interacting particles in any number of dimensions in an attractive external ... | Paramagnetic impurities; Eigenstates | 1966 |

Flynn, John J. | Federalism and viable state government: the history of Utah's Constitution | The decade of the 1960's has witnessed, thus far, a sharp upswing of interest in the state of the states. Financial crisis, political paralysis, reapportionment, and the continued trend of federal intervention in heretofore "local" affairs have forced believers in the federal idea to reexamine the s... | Constitution, Law; History | 1966 |

Miller, Joel Steven | Using fission | Atoms are just like people, both are lazy. Energy is a measure of work, i.e., more work implies more energy. Atoms do not like to work, hence they try to reduce the energy in their atomic system. For different elements the energy reduction occurs by reaction, e.g., an energetic sodium atom reacts w... | Uranium-235; Uranium-238 | 1966 |

Capecchi, Mario R. | N-formylmethionyl-sRNA as the initiator of protein synthesis. | A bizarre fast about Nterminal groups of bacterial proteins. Instead of a random mixture, that the great majority of N-terminal groups were either methionine or alanine. This finding suggested that methionine and alanine constituted start signals for the initiation of polypeptide chains. Alternative... | Electrophoresis; Formates; In Vitro; Methionine | 1966-01-01 |

Mattis, Daniel C. | Soluble extension of the Ising model | In this note we wish to relate a somewhat trivial, but surprising, soluble extension of the multidimensional Ising model. Our extension was motivated by recent experiments on a real material, dysprosium aluminum garnet (DyAlG), which closely resembles an ideal three-dimensional Ising model,1 except ... | Dysprosium aluminum garnet; Ising spin | 1966-05 |

Capecchi, Mario R. | Initiation of E. coli proteins. | Recent experiments and theoretical arguments suggest that formylmethionyl sRNA is employed as an initiator of protein synthesis. Studies also indicated that other phage proteins synthesized in the in vitro system were initiated with formylmethionine. These observations provided a basis for believin... | Alanine; Chromatography, Paper; Dipeptides | 1966-06 |
