Nuclear spins, magnetic moments and quadrupole moments of Cu isotopes from N = 28 to N = 46: probes for core polarization effects
Nuclear spins magnetic moments quadrupole moments Cu isotopes probes core polarization effects
2010/12/31
Measurements of the ground-state nuclear spins, magnetic and quadrupole moments of the copper isotopes from 61Cu up to 75Cu are reported. The experiments were performed at the ISOLDE facility, using t...
A precise extraction of the induced polarization in the 4He(e,e'p)3H reaction
precise extraction the induced polarization the 4He(e,e'p)3H reaction
2010/12/29
We measured with unprecedented precision the induced polarization Py in 4He(e,e'p)3H at Q^2 = 0.8 (GeV/c)^2 and 1.3 (GeV/c)^2. The induced polarization is indicative of reaction-mechanism effects beyo...

Electron-atom bremsstrahlung double differential cross section polarization correlations
2010/11/16
The leading-order electron-atom bremsstrahlung is investigated within the rigorous relativistic approach based on the partial-wave representation of the Dirac wave functions in the external atomic fi...
Leading-Order Determination of the Gluon Polarization from high-$p_T$ Hadron Electroproduction
Lepton-Nucleon Scattering Deep Inelastic Scattering QCD gluon polarization
2010/3/15
Longitudinal double-spin asymmetries of charged hadrons with high transverse momentum $p_T$ have been measured in electroproduction using the \hermes\ detector at \hera. Processes involving gluons in ...
Study of second-class currents effects on polarization characteristics in quasi-elastic neutrino (anti-neutrino) scattering by nuclei
Second-class currents nuclei polarization neutrino scattering spin asymmetry and en correlation
2010/4/8
The differential cross section of quasi-elastic neutrino scattering by nuclei is computed. The numerical analysis of energy dependence of the spin asymmetry, the angular electron-neutrino (en) correla...

2010/4/9
A new experimental value, M = 0.06925 \pm 0.00281, of the peak of the quadrupole form factor FQ(q) is obtained by fitting the straight line relation found between the peak values of both T21(q) and FQ...

2010/10/25
In the present work we discuss the contribution of the vacuum polarization on the nuclear pairing, in the context of the relativistic Hartree-Fock-Bogoliubov (HFB) approximation. The polarization effe...

Antihyperon Polarization Inclusive Processes High Energies
2010/10/19
We propose a model that we believe is the main source of the antihyperon polarization in high-energy protonnucleus inclusive reactions. The polarization is originated by the final-state interactions b...
