Stopping power of antiprotons in H, H2, and He targets
The stopping power of antiprotons in atomic and molecular hydrogen as well as helium was calculated in an impact-energy range from 1 keV to 6.4 MeV. In the case of H2 and He the targets were described with a single-active electron model centered on the target. The collision process was treated with the close-coupling formulation of the impact-parameter method. An extensive comparison of the pre...
متن کاملCollisions of low-energy antiprotons with molecular hydrogen: ionization, excitation and stopping power
A time-dependent coupled-channel approach was used to calculate ionization, excitation, and energyloss cross sections as well as energy spectra for antiproton and proton collisions with molecular hydrogen for impact energies 8<E< 4000 keV.
متن کاملComprehensive analysis of the stopping power of antiprotons and negative muons in He and H2 gas targets
A comprehensive analysis of the stopping power of antiprotons and negative muons in He and H2 gas targets for projectile velocities (equivalent antiproton energies) ranging from about 0.1 to 10 au (0.25 keV to 2.5 MeV) is performed. Recent experimental data are contrasted with theoretical results obtained from different approaches. The electronic stopping power is evaluated within the coupled-s...
متن کاملNuclear Interactions of Antiprotons with Aluminium and Carbon
The development of high-energy accelerators is providing increasingly intense beams of several particles. In particular, the recent availability of negative pions and antiprotons at CERN has made it possible to study their interactions with complex nuclei. At present there exist three ways of investigating the interactions of particles such as antiprotons with complex nuclei. We refer to a) tra...
متن کاملThe Comparison of the shares of stopping power in a soft tissue-equivalent material
Introduction: Proton therapy is a type of radiation treatment that it uses protons to treat cancer. Because of the protons’ unique ability to distribute the radiation dose more directly to the tumor, it minimizes the damage to nearby healthy tissues. The rate of energy loss by the ion in the target is called stopping power. The total stopping power is sum nuclear and electroni...
