Measured Lifetimes of Selected Metastable Levels of Arq+ Ions (Q=2, 3, 9, and 10) Stored in an Electrostatic Ion-Trap
(American Physical Society, 1994)
Metastable multiply charged argon ions produced in, and extracted from, an electron cyclotron resonance ion source were captured from the beam into an electrostatic (Kingdon) ion trap by rapidly pulsing the potential of ...
Medium Effects on Subthreshold Kaon Production in Heavy-Ion Collisions
(American Physical Society, 1994)
The relativistic transport model is extended to include the kaon degree of freedom. We also take into account the density dependence of the kaon effective mass in nuclear matter and the rescattering of kaons by nucleons. ...
Excitation function of nucleon and pion elliptic flow in relativistic heavy-ion collisions
(American Physical Society, 1999)
Within a relativistic transport model for heavy-ion collisions, we show that the recently observed characteristic change from out-of-plane to in-plane elliptic flow of protons in midcentral Au+Au collisions as the incident ...
Elastic scattering of the proton drip-line nucleus F-17
(American Physical Society, 2005)
Precision data have been obtained for the elastic scattering of F-17 on C-12 and N-14 at 10 MeV/nucleon to clarify the reaction mechanism for loosely bound nuclei at low energies and to assess the validity of a double-folding ...
Reversing entanglement change by a weak measurement
(American Physical Society, 2010)
Entanglement of a system changes due to interactions with the environment. A typical type of interaction is amplitude damping. If we add a detector to monitor the environment and only select the no-damping outcome, this ...
Coherence-induced entanglement
(American Physical Society, 2005)
We show how atomic coherence can lead to entanglement between two thermal fields at a temperature T. We first show that the passage of a three-level atom in V configuration without coherence cannot create entanglement. ...
Quenching Collisions of Low-Energy Metastable Multiply-Charged Argon Ions
(American Physical Society, 1994)
Quenching rates have been measured for selected metastable levels of Ar(q+) ions (q = 2, 3, 9, and 10) stored in a Kingdon ion trap, with mean energies of 262q eV and 181q eV. Effective quenching cross sections derived ...
Partonic coalescence in relativistic heavy ion collisions
(American Physical Society, 2003)
Using a covariant coalescence model, we study hadron production in relativistic heavy ion collisions from both soft partons in the quark-gluon plasma and hard partons in minijets. Including transverse flow of soft partons ...
Flux Motion in Anisotropic Type-Ii Superconductors Near H(c2)
(American Physical Society, 1993)
Flux motion in anisotropic type-II superconductors is studied in the framework of the time-dependent Ginzburg-Landau theory. Expressions for the flux-flow resistivity tensor (including all the longitudinal and Hall elements) ...
Torque magnetometry study of metamagnetic transitions in single-crystal HoNi(2)B(2)C at T approximate to 1.9 K
(American Physical Society, 2007)
Metamagnetic transitions in single-crystal rare-earth nickel borocarbide HoNi(2)B(2)C have been studied at T approximate to 1.9 K with a Quantum Design torque magnetometer. This compound is highly anisotropic with a variety ...
