Dispersive coupled-channel analysis of nucleon scattering from 232 Th up to 200 MeV
(American Physical Society, 2005-08-01)
An isospin-dependent coupled-channels optical model potential containing a dispersive term (including nonlocal contribution) is used to simultaneously fit the available experimental database (including strength functions ...

Dispersive spherical optical model of neutron scattering from 27 Al up to 250 MeV
(American Physical Society, 2002-03-01)
A spherical optical model potential (OMP) containing a dispersive term is used to fit the available experimental database of s(u) and sT for n127Al covering the energy range 0.1–250 MeV using relativistickinematics ...

Approximate Lane consistency of the dispersive coupled-channels potential for actinides
(The American Physical Society, 2007)
A previously derived dispersive coupled-channels optical model potential for nucleon scattering on 232Th and 238U nuclei [Capote, Soukhovitskii, Quesade, and Chiba, Phys. Rev. C 72, 064610 (2005)] has been tested against ...

Instantons and the ⟨A2⟩ condensate
(American Physical Society, 2002-12-01)
We argue that the ⟨A2OPE⟩ condensate found in the Landau gauge on lattices, when an operator product expansion of Green’s functions is performed, might be explained by instantons. We use cooling to estimate the instanton ...

Plasma-enhanced chemical vapor deposition of SiO2 from a Si(CH3)3Cl precursor and mixtures Ar/O2 as plasma gas
(AVS Science and Technology Society, 2003-07)
Silicon dioxide thin films have been prepared at room temperature by remote plasma-enhanced chemical vapor deposition in a downstream reactor by using Si(CH3)3Cl as a volatile precursor and a microwave electron cyclotron ...

Analytical expressions for the dispersive contributions to the nucleon-nucleus optical potential
(American Physical Society, 2003-06-01)
Analytical solutions of dispersion relations in the nucleon-nucleus optical model have been found for both volume and surface potentials. For the energy dependence a standard Brown-Rho function has been assumed for both ...

Optimal filter systems for photometric redshift estimation
(IOP Publishing Ltd., 2009)
In the coming years, several cosmological surveys will rely on imaging data to estimate the redshift of galaxies, using traditional filter systems with 4-5 optical broad bands; narrower filters improve the spectral resolution, ...

Transparent expression of the A2 condensate’s renormalization
(American Physical Society, 2003-12-01)
We give a more transparent understanding of the vacuum expectation value of the renormalized local operator A2 by relating it to the gluon propagator integrated over the momentum. The quadratically divergent perturbative ...
