Measurements of the neutron electric to magnetic form factor ratio G_(En)/G_(Mn) via the ^2H(e, e'n)^1H reaction to Q^2 = 1.45 (GeV/c)^2 [PDF]

open access: yes, 2006
We report values for the neutron electric tomagnetic form factor ratio,G_(En)/G_(Mn), deduced frommeasurements of the neutron’s recoil polarization in the quasielastic ^2H(e, e'n)^1H reaction, at three Q^2 values of 0.45, 1.13, and 1.45 (GeV/c)^2.

Charged Current Neutrino Nucleus Interactions at Intermediate Energies

open access: yes, 2006
We have developed a model to describe the interactions of neutrinos with nucleons and nuclei, focusing on the region of the quasielastic and Delta(1232) peaks. We describe neutrino nucleon collisions with a fully relativistic formalism which incorporates

Time-Temperature Superposition of Structural Relaxation in a Viscous Metallic Liquid [PDF]

open access: yes, 1999
Bulk metallic glass-forming Pd40Ni10Cu30P20 has been investigated in its equilibrium liquid by quasielastic neutron scattering. The quasielastic signal exhibits a structural relaxation as known from nonmetallic viscous liquids.

Molecular spin-liquid state in spin-3/2 frustrated spinel HgCr$_2$O$_4$

open access: yes, 2011
A hexamer-type spin excitation seen in spinel chromates $A$Cr$_2$O$_4$ ($A$ = Mg, Zn, or Cd) is the representative spin-liquid-like state caused by geometrical frustration.

Inclusive quasielastic electron scattering on $^6$He: a probe of the halo structure [PDF]

open access: yes, 2000
We investigate inclusive electron scattering reactions on two-neutron halo nuclei in the quasielastic region. Expressions for the cross section and structure functions are given assuming that the halo nucleus can be described as a three-body system ...

Elastic scattering of 17F, 17O and 19F on a heavy target in microscopic continuum discretized coupled-channels method

open access: yes, 2014
Background: Microscopic description of the projectile, based on an effective NN interaction, in a microscopic CDCC (MCDCC) model [PRL 111, 082701 (2013)] has been successfully applied to the 7Li+208Pb scattering. Purpose: The MCDCC method is applied to

Nuclear halo structure from quasielastic charge-exchange reactions

open access: yes, 2005
Neutron and proton densities in the nuclear periphery are investigated within (p,n) charge-exchange isobar transitions. For this purpose we have developed parameter-free optical potentials with a detailed treatment of the in-medium $t_{\tau}$ part of the

Performance of the neutron polarimeter NPOL3 for high resolution measurements [PDF]

open access: yes, 2005
We describe the neutron polarimeter NPOL3 for the measurement of polarization transfer observables $D_{ij}$ with a typical high resolution of $\sim$300 keV at $T_n$ $\simeq$ 200 MeV. The NPOL3 system consists of three planes of neutron detectors. The

The measurement of self-diffusion coefficients in liquid metals with quasielastic neutron scattering

open access: yesEPJ Web of Conferences, 2015
Quasielastic incoherent neutron scattering (QENS) has proven to be a versatile tool to study self diffusion of atoms in liquid metals. Here it is shown, that coherent contributions to the signal in the small q limit appear as a flat and energy ...

Theoretical study of lepton events in the atmospheric neutrino experiments at SuperK

open access: yes, 2009
Super-Kamiokande has reported the results for the lepton events in the atmospheric neutrino experiment. These results have been presented for a 22.5kT water fiducial mass on an exposure of 1489 days, and the events are divided into sub-GeV, multi-GeV and
