Double-differential Cross-sections, Yields
Different fields and disciplines in Science and Technology are imposing more stringent and accurate measurements of the proton and neutron total and differential cross-sections in the intermediate-energy range, from a few dozens of MeV up to a few GeV. Such measurements could be performed in facilities disposing of proton or light ion beams (namely facilities to produce Radioactive Nuclear Beam...
متن کاملNormalization of neutron-proton differential cross sections
The np differential cross section below 350 MeV neutron laboratory energy is studied using the energy-dependent Nijmegen partial-wave analysis PWA93. We analyze in detail three experiments, performed at LAMPF, at TRIUMF, and at the TSL facility in Uppsala. The issue of normalization of np cross sections is discussed, where we distinguish between measured and calculated normalizations. This anal...
متن کاملAttachment cross sections of protonated water clusters.
The attachment of water molecules onto size selected protonated water clusters has been experimentally investigated. Absolute attachment cross sections are measured as a function of cluster size, collision energy, and initial cluster temperature. Although thermal evaporation is ruled out in our experiment, attachment cross sections become significantly smaller than hard sphere cross sections as...
متن کاملFragmentation cross sections of protonated water clusters.
We have measured fragmentation cross sections of protonated water cluster cations (H(2)O)(n=30-50)H(+) by collision with water molecules. The clusters have well-defined sizes and internal energies. The collision energy has been varied from 0.5 to 300 eV. We also performed the same measurements on deuterated water clusters (D(2)O)(n=5-45)D(+) colliding with deuterated water molecules. The main f...
