Single Muon Production And Implications For Charm In √Sn N = 200 Gev Au+Au Collisions, Andrew Miles Glenn
Single Muon Production And Implications For Charm In √Sn N = 200 Gev Au+Au Collisions, Andrew Miles Glenn
Doctoral Dissertations
The PHENIX experiment, located at the Brookhaven National Laboratory’s Rela- tivistic Heavy Ion Collider, is designed to study high energy proton+proton and nu- cleus+nucleus collisions in order to characterize hot and dense nuclear matter. This dissertation presents the first analysis of single muon production in √sN N = 200 GeV Au+Au reactions. Implications of the forward rapidity measurements for charm pro- duction are discussed. Motivation for charm production measurements and the role of open charm in characterizing the medium created in relativistic heavy ion collisions are presented, and the importance of measurements at forward rapidity is established. The results of …
Metallic Ferroelectricity And Superconductivity In The Transition Metal Oxide Pyrochlore Cd2Re2O7, Jian He
Metallic Ferroelectricity And Superconductivity In The Transition Metal Oxide Pyrochlore Cd2Re2O7, Jian He
Doctoral Dissertations
Single crystalline samples of transition metal oxide Cd2Re2O7, the first superconductor among pyrochlore oxides with general formula A2B2O7 and the first example of “ferroelectric metal” theoretically proposed by P.W. Anderson and E.I. Blount back in 1960s, have been grown using vapor transport and carefully characterized, regarding its chemical stoichiometry and structure. In addition to the superconductivity transition, two normal state phase transitions and the anomalous high temperature phase have been comprehensively investigated, by means of transport, thermodynamic and spectroscopy techniques. The system undergoes a subtle continuous cubic-to-tetragonal phase transition …
Fundamental Investigations And Analysis Of Chiral Matter Using Simple Spectroscopic Techniques, Rodney Jamel Sullivan
Fundamental Investigations And Analysis Of Chiral Matter Using Simple Spectroscopic Techniques, Rodney Jamel Sullivan
Doctoral Dissertations
Fundamental investigations of circular dichroism were performed on (R)-(+)-3- methylcyclopentanone, (R)-(-)-2-butylamine, and (S)-(+)-2-butylamine in the liquid and vapor phase to show that solvents often have a structure-masking effect on the circular dichroism for a given molecule. Also, the solid state circular dichroism of cubic sodium chlorate crystals was successfully measured in the midst of adverse experimental circumstances. With these single photon circular dichroism studies at hand, a new technique for measuring circular dichroism was introduced for an advanced investigation of (R)-(+)-3-methylcyclopentanone. The resonance enhanced multiphoton ionization of (R)-(+)-3-methylcyclopentanone was performed …
Alpha And Gamma-Ray Spectroscopic Studies Of Au, Pt, And Ir Nuclei Near The Proton Dripline, Tuck-Meng Goon
Alpha And Gamma-Ray Spectroscopic Studies Of Au, Pt, And Ir Nuclei Near The Proton Dripline, Tuck-Meng Goon
Doctoral Dissertations
This dissertation reports the observation of α-decay and in-beam level structures in the neutron-deficient nuclei 176,174Au, 173,174Pt, and 175Ir from an experiment which was performed at Argonne National Laboratory (ANL). A beam of 84Sr projectiles was used to bombard 92,94,96Mo targets. From these reactions, the 176,178,180Hg compound nuclei were made which eventually decayed into more than 20 product nuclei. The experiment was performed with the Atlas accelerator and utilized the Gammasphere array at the target position in conjunction with the Fragment Mass Analyzer (FMA) for mass identification and a Double-Sided Silicon Strip Detector (DSSD), …
