Production and Validation of Isotope Production Cross Section Libraries for Neutrons and Protons to 1.7 GeV
For validation and development of codes and for modeling isotope production in high power accelerators and APT Materials studies, we have produced experimental, calculated, and evaluated activation libraries for interaction of nucleons with nuclides covering about a third of all natural elements. For targets considered here, our compilation of experimental data is the most complete we are aware...
متن کاملInclusive production of protons , anti - protons and neutrons in p + p collisions at 158 GeV / c beam momentum
New data on the production of protons, anti-protons and neutrons in p+p interactions are presented. The data come from a sample of 4.8 million inelastic events obtained with the NA49 detector at the CERN SPS at 158 GeV/c beam momentum. The charged baryons are identified by energy loss measurement in a large TPC tracking system. Neutrons are detected in a forward hadronic calorimeter. Inclusive ...
متن کاملRadiative capture of neutrons by protons
A model-independent irreducible tensor approach to p(n, γ)d is presented and an explicit form for the spin-structure of the matrix M for the reaction is obtained in terms of the Pauli spin-matrices σ(n) and σ(p). Expressing the multipole amplitudes in terms of the triplet → triplet and singlet → triplet transitions, we point out how the initial singlet and triplet contributions to the different...
متن کاملBuilding light nuclei from neutrons, protons, and pions
An effective theory is a systematic approximation to some underlying dynamics (which may be known or unknown) that is valid in some specified regime. An effective theory is not a model, since its systematic character means that, in principle, predictions of arbitrary accuracy may be made. However, if this is to be true then a small parameter, such as the α of quantum electrodynamics, must gover...
متن کاملDecay of protons and neutrons induced by acceleration
We investigate the decay of accelerated protons and neutrons. Calculations are carried out in the inertial and coaccelerated frames. Particle interpretation of these processes are quite different in each frame but the decay rates are verified to agree in both cases. For the sake of simplicity our calculations are performed in a two-dimensional spacetime since our conclusions are not conceptuall...
