The self-consistent general relativistic solution for a system of degenerate neutrons, protons and electrons in beta-equilibrium
Neutron Star Electrodynamics General Relativistic Thomas-Fermi treatment
2011/7/21
We present the self-consistent treatment of the simplest, nontrivial, self-gravitating system of degenerate neutrons, protons and electrons in $\beta$-equilibrium within relativistic quantum statistic...
Measurements of nuclear $\gamma$-ray line emission in interactions of protons and $\alpha$ particles with N, O, Ne and Si
Measurements of nuclear $\gamma$-ray line emission interactions of protons $\alpha$ particles with N, O, Ne and Si
2011/1/4
$\gamma$-ray production cross sections have been measured in proton irradiations of N, Ne and Si and $\alpha$-particle irradiations of N and Ne. In the same experiment we extracted also line shapes fo...
Radiative pi0 photoproduction on protons in the Delta+(1232) region
pi0 photoproduction protons Delta+(1232) region
2010/3/15
The reaction gamma p -> p pi0 gamma' has been measured with the Crystal Ball / TAPS detectors using the energy-tagged photon beam at the electron accelerator facility MAMI-B. Energy and angular differ...
Primakoff effect in eta-photoproduction off protons
Primakoff effect eta-photoproduction off protons
2010/3/15
We analyse data on forward eta-meson photoproduction off a proton target and extract the eta to gamma gamma decay width utilizing the Primakoff effect. The hadronic amplitude that enters into our anal...
Surveying post-saddle nuclear dissipation with protons and α particles as probes
nuclear dissipation light charged-particle multiplicity isospin effect
2009/12/24
Using a Langevin model, we calculate post-saddle proton and α-particle multiplicities as a function of the post-saddle dissipation strength (β) for the heavy systems 234Cf, 240Cf, 246Cf and 240U. We f...
φ-meson photoproduction off the protons by using linearly polarized photons in the mid- to higher-t regimes at threshold energies
photoproduction of φ-mesons linearly-polarized photons polarization observables
2009/11/24
Observables from vector meson photoproduction by linearly-polarized photons can be expressed in term of bilinear combinations of helicity amplitudes parameterized by the Spin Density Matrix Elements (...

An international group of physicists working at the Los Alamos Laboratory in the US has used a laser to generate 67.5 MeV protons – the highest-energy protons yet produced in this way. Their work poin...
A study of radiation effects of 9 and 12MeV protons on Chinese CMOS image sensor degradation
semiconductor technology CMOS image sensor proton irradiation average brightness TRIM simulation
2009/8/17
The 9 and 12MeV proton irradiations of the Chinese CMOS Image Sensor in the fluence range from 1×109 to 4×10×10cm-2 and 1×109 to 2×1012cm-2 have been carried out respectively. The color pictures and...
