متن کاملElectroproduction of Hadrons from Deuterium
The inclusive electroproduction of hadrons is measured from hydrogen and deuterium targets. The exchanged virtual photons are in the kinematic range -0.25 > cl2 > -3.00 GeV2, 12 <s < 30 GeV2. Hadrons which travel in the direction of the virtual photon in the virtual photon-nucleon center-of-mass system are detected. A striking difference from photoproduction is observed in the excess of positiv...
متن کاملPionic deuterium
The strong-interaction shift πD 1s and broadening Γ πD 1s in pionic deuterium have been determined in a high statistics study of the πD(3p-1s) X-ray transition using a high-resolution crystal spectrometer. The pionic deuterium shift will provide constraints for the pion-nucleon isospin scattering lengths extracted from measurements of shift and broadening in pionic hydrogen. The hadronic broade...
متن کاملDeuterium-deuterium nuclear cross-sections in insulator and metallic environments
The three-dimensional Thomas-Fermi (TF) model is used to simulate the variation of the d+d → t + p cross-section at low impact energies, when the target deuterium nucleus is embedded in metallic or insulator environments. Comparison of the computational results to recent experiments demonstrates that even though the TF model can explain some increase in the low energy cross section for metallic...
