Superallowed 0(+)-> 0(+) nuclear beta decays: A new survey with precision tests of the conserved vector current hypothesis and the standard model
(American Physical Society, 2009)
A new critical survey is presented of all half-life, decay-energy, and branching-ratio measurements related to 20 superallowed 0(+)-> 0(+)beta decays. Compared with our last review, there are numerous improvements: First, ...
Isoscalar giant resonances for nuclei with mass between 56 and 60
(American Physical Society, 2006)
The giant resonance region from 10 MeV < E-x < 62 MeV in Fe-56, Ni-58, and Ni-60 has been studied with inelastic scattering of 240 MeV alpha particles at small angles, including 0 degrees. Most of the expected isoscalar ...
Dilepton production in schematic causal viscous hydrodynamics
(American Physical Society, 2011)
Assuming that in the hot dense matter produced in relativistic heavy-ion collisions, the energy density, entropy density, and pressure as well as the azimuthal and space-time rapidity components of the shear tensor are ...
Astrophysical S(E) factor of the (15)N(p, alpha)(12)C reaction at sub-Coulomb energies via the Trojan horse method
(American Physical Society, 2007)
The low-energy bare-nucleus cross section for (15)N(p, alpha)(12)C is extracted by means of the Trojan horse method applied to the (2)H((15)N,alpha(12)C)n reaction at E(beam) = 60 MeV. For the first time we applied the ...
Spin Hall and spin-diagonal conductivity in the presence of Rashba and Dresselhaus spin-orbit coupling
(American Physical Society, 2004)
We investigate the spin-current linear response conductivity tensor to an electric field in a paramagnetic two-dimensional electron gas with both Rashba and Dresselhaus spin-orbit coupling in the weak scattering regime ...
Gap anisotropy and universal pairing scale in a spin-fluctuation model of cuprate superconductors
(American Physical Society, 2008)
We consider the evolution of d(x)(2)-y(2) pairing, mediated by nearly critical spin fluctuations, with the coupling strength. We show that the onset temperature for pairing, T(*), smoothly evolves between weak and strong ...
Mass, quark-number, and root s(NN) dependence of the second and fourth flow harmonics in ultrarelativistic nucleus-nucleus collisions
(American Physical Society, 2007)
We present STAR measurements of the azimuthal anisotropy parameter v(2) for pions, kaons, protons, Lambda,(Lambda) over bar,Xi+ (Xi) over bar, and Omega+ (Omega) over bar, along with v(4) for pions, kaons, protons, and ...
Astrophysical S factor for C-13(p,gamma)N-14 and asymptotic normalization coefficients
(American Physical Society, 2002)
We reanalyze the C-13(p,gamma)N-14 radiative capture reaction within the R-matrix approach. The low-energy astrophysical S factor has important contributions from both resonant and onresonant captures. The normalization ...
Correlated two-proton decay from (10)C
(American Physical Society, 2008)
The decay of (10)C excited states to the 2p + 2 alpha exit channel has been studied using inelastic excitation of a secondary (10)C beam. The decay sequences leading to the 2p + 2 alpha final state are determined for the ...
Electrical signature of magnetic domain-wall dynamics
(American Physical Society, 2011)
Current-induced domain-wall dynamics is studied in a thin ferromagnetic nanowire. The domain-wall dynamics is described by simple equations with four parameters. We propose a procedure to unambiguously determine these ...
