In this paper, we investigated the produced cusp in the Λ0 p  invariant mass spectrum from the Κ-d→ Λ0 pπ- reaction at kenergies of 1.45 and 1.65 GeV. According to these calculations the peak of spectrum was around MΛp=2130 MeV /c2 and the width was Γ=13MeV. To interpret this cusp we applied a coupled-channel treatment for the two decay processes Λp→Λp and ΣN→Λp. The results of the inelastic ch...

The present status of experimental data of proton-induced reactions is reviewed, with particular attention to total reaction cross section, elastic and inelastic scattering cross section, double-differential particle production cross section, isotope production cross section, and activation cross section.

The state-to-state dynamics of high-n Rydberg H-atom scattering with para-H2 at the collision energies of 0.45 and 1.07 eV have been studied using the H-atom Rydberg tagging time-of-flight technique. Both the inelastic scattering and reactive scattering are observed in the experimental time-of-flight spectra. The products H2(v', j' = odd) come only from reactive scattering and present clearly f...

Full quantum-state resolved scattering of a highly excited Rydberg H atom with D2 has been carried out using the Rydberg H-atom time-of-flight method. A detailed analysis of the experimental results shows that both inelastic and reactive scatterings are significant in the Hn-D2 collisions, and nuclear spin is conserved in the inelastic scattering process. The differential cross sections for the...

We calculate the cross sections of the elastic and inelastic breakup modes for the inclusive breakup reaction 28 Si(8 B, 7 Be) at beam energies between 10-40 MeV/nucleon within a direct fragmentation model formulated in the framework of the post form distorted-wave Born-approximation. In contrast to the case of the stable isotopes, the inelastic breakup mode is found to contribute only up to 30...

The powerful white neutron spectrum from Gelina is used for the investigation of gamma ray production cross sections in the reaction 52Cr(n,n'gamma)52Cr. The gamma rays from the inelastic process are detected with two large volume HPGe detectors placed at 110 degrees and 150 degrees with respect to the beam direction. The neutron flux has been measured with a 235U fission chamber. For the main ...

Quasielastic and inelastic neutron scattering have been highlighted as excellent tools for studying the hydration of cement components. Here, the complimentary application of inelastic and time-resolved quasielastic neutron scattering to investigate the reaction kinetics during the crucial first 24 h of hydration will be highlighted. Some recent results include the interaction of tricalcium and...
