Investigation of the anomaly in η-photoproduction off the neutron
photoproduction eta-meson narrow nucleon resonance
2009/11/24
Quasi-free photoproduction of η-mesons off the neutron and off the proton has been studied using a deuterium target and bremsstrahlung photons produced by MAMI-C with incident energies up to 1.5 GeV...
Investigation of PL properties of C-doped SiO2/Si samples after high energy Pb ion irradiation
heavy ion irradiation, carbon ion implantation, photoluminescence (PL) spectra
2009/8/14
Amorphous SiO2 thin films with about 400—500 nm in thickness were thermally grown on single crystalline silicon. These SiO2/Si samples were firstly implanted at room temperature (RT) with 100 keV carb...
Steady state investigation on neutronics of a molten salt reactor considering the flow effect of fuel salt
MSR steady state neutronics flow effect delayed neutron precursors
2009/8/14
The Molten Salt Reactor (MSR), one of the `Generation IV' concepts, is a liquid-fuel reactor, which is different from the conventional reactors using solid fissile materials due to the flow effect of...
Theoretical investigation of the structure of 19N
exotic nuclei nuclear structure 19N shell model
2009/8/14
We have employed the shell model and Skyrme-Hartree-Fock methods to investigate the structure of the neutron-rich nucleus 19N. The level scheme of 19N from the shell-model calculation with the WBT int...
Investigation of the Ground State Features of Some Excotic Nuclei by Using Effective Skyrme Interaction
Hartree-Fock calculations nucleon--nucleon interactions charge distribution
2010/4/9
Nuclear many-body system is usually described through a mean-field built upon a nucleon-nucleon effective interaction. This interaction has been developed over the years for both stable and unstable n...
An Investigation of Temperature Effect on Phonon Dispersion Spectra of Ni by Molecular Dynamics Simulation
Molecular dynamics simulation embedded atom method phonon dispersion spectra dynamical matrix
2010/4/8
Lattice vibrations have great influences on physical and mechanical properties of materials. In this study, changes of acoustic phonon frequencies of Ni model system with temperature was investigated ...
An Investigation of the Effects of Hydrogen on Local Strain Fields and Structural Disorder-to-Order Transition in Hydrogenated Amorphous Silicon
Amorphous silicon atomic-level stress defects topological disorder local order strain-fields
2010/4/9
This study utilizes the fluctuations in the mean silicon-silicon near neighbour distances and local atomic-level stresses to study the chemically-induced disorder-to-order transition in hydrogenated a...
The Investigation of Screening of Chromoelectric and Chromomagnetic Fields in Noncovariant Gauges
Thermal Quantum Chromodynamics Quark-gluon Plasma Lightcone Gauge Temporal Gauge Mandelstam-Leibbrandt Prescription Gluon Screening Masses
2010/4/9
According to Thermal Quantum Chromodynamics (TQCD) hadron matter may exist in the form of quark-gluon plasma (QGP) at high temperatures and densities. The aim of the present work is to investigate the...
Investigation of Excited Levels in 193Ir From the Beta Decay of 193Os
Excited Levels 193Ir the Beta Decay of 193Os
2010/10/15
The excited states in 193Ir populated by the b¡ decay of 193Os were investigated via g-g coincidence analysis. Three levels at 517, 563 and 621 keV, previsouly seen only in nuclear reaction stud...
