Relationship between electron density and effective densities of body tissues for stopping, scattering and nuclear interaction of proton and ion beams
electron density body tissues proton and ion beams
2011/9/9
In treatment planning of charged-particle radiotherapy, patient heterogeneity is normally modeled as variable-density water to best reproduce the stopping power. This water-based model would cause sub...
Although the idea of proton Computed Tomography (pCT) is not new, it is currently not available. It is still unknown if the image quality of pCT is sufficient for localizing tumors and if the accuracy...
The Proton Momentum Distribution in Water and Ice
The Proton Momentum Distribution Water Ice
2010/10/18
Deep Inelastic Neutron Scattering (Neutron Compton Scattering), is used to measure the momentum distribution of the protons in water from temperatures slightly below freezing to the supercritical phas...
Extensions of the Extrema Bounds for the Pomeron Intercept to Meson-Proton, Gamma-Proton and Gamma-Gamma Scattering
the Extrema Bounds the Pomeron Intercept Meson-Proton Gamma-Proton Gamma-Gamma Scattering
2010/10/19
Making use of the extrema bounds for the soft pomeron intercept, recently determined by fits to pp and ¹pp data (from both accelerator and cosmic-ray experiments), we investigate the total cross ...
The Flavor Asymmetry in the Polarized Proton Sea
The Flavor Asymmetry the Polarized Proton Sea
2010/10/19
We perform a careful study on the effect of the Pauli blocking to the light polarized antiquark structure of the proton sea. We develop the formal expressions for the polarized antiquark distributions...
Calculation of the Reaction Cross-Section for Proton-Nucleus Using Recently Optical Potential
Cross-Section Proton-Nucleus Recently Optical Potential
2010/4/19
The eikonal approximation is used to calculate the reaction cross-section for proton scattering from different nuclei. The imaginary proton - nucleus optical potential is derived from relativistic mea...
