Density of states and order parameter in dirty anisotropic superconductors
(American Physical Society, 1996)
We analyze in detail how the scattering by nonmagnetic impurities affects the shape and amplitude of the order parameter (OF) and the density of states in anisotropic superconductors in the framework of BCS theory. Special ...
Electrical resistivity and thermopower of single-crystal RNi2B2C (R=Dy, Ho, Er, Tm) magnetic superconductors
(American Physical Society, 1997)
The in-plane resistivity rho and thermopower S of single crystal RNi2B2C (R=Dy, Ho, Er, Tm) has been measured from 4 to 300 K. The resistivity is linear in temperature from about 100 to 300 K, but the low-temperature ...
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 ...
Excited-Level Lifetimes and Hyperfine-Structure Measurements on Ions using Collinear Laser Ion-Beam Spectroscopy
(American Physical Society, 1994)
The mean lifetimes tau of the Ca II 4p P-2(1/2) and 4p P-2(3/2) levels, and the Cl-35 II 4p' F-1(3) level, have been measured by a variant of the collinear laser-ion-beam lifetime technique applied previously to the Ar II ...
Magnetic dipole transition rates from measured lifetimes of levels of Be-like and B-like argon ions
(American Physical Society, 1998)
The lifetimes of the 1s(2)2s2p P-3(2) level of Ar XV and 1s(2)2s(2)2p P-2(3/2) of Ar XIV have been measured using metastable Ar14+ and Ar13+ ions produced by an electron cyclotron resonance ion source, which were subsequently ...
Folding model analysis of the excitation of low-lying states and the high energy octupole resonance in Sn-116 by 240 MeV alpha scattering
(American Physical Society, 1998)
The sum rule strength of the high energy octupole resonance (HEOR) and the transition rates of low-lying 2(+) and 3(-) states of Sn-116, excited by 240 MeV alpha scattering, have been determined from deformed potential and ...
One-And-A-Half-Centered Expansion Method in Charge-Transfer Calculations of Proton-Hydrogen Scattering
(American Physical Society, 1993)
In this paper, we undertake a feasibility study of improving the one-and-a-half-centered expansion (OHCE) method of Reading, Ford, and Becker [J. Phys. B 14, 1995 (198 1)
P(t) Dependence of Transverse Flow in Relativistic Heavy-Ion Collisions
(American Physical Society, 1996)
The strength of transverse flow is examined as a function of transverse momentum p(t) using a simple, transversely moving thermal model and a more realistic, relativistic transport model. It is shown that the p(t) dependence ...
Hadron Widths in Mixed-Phase Matter
(American Physical Society, 1994)
We derive classically an expression for a hadron width in a two-phase region of hadron gas and quark-gluon plasma (QGP). The presence of QGP gives hadrons larger widths than they would have in a pure hadron gas. We find ...
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. ...
