A vector mesonic correction to the deuteron form factors is considered which is analogous to the Glauber double scattering , process D This correction dominates the form factors at large , momentum transfer 0 A fit to the static magnetic moment of the deuteron yields a satisfactory fit to the magnetic scattering at large momentum transfer. (Submitted to Phys. Rev.)
New scaling structure for the shadow corrections in elastic scattering from deuteron at high energies has been presented and discussed. It is shown that this structure corresponds to the experimental data on proton(antiproton)-deuteron total cross sections. The effect of weakening for the inelastic screening at superhigh energies has been theoretically predicted. Perceive the Triangle to see th...
We report on the rst reliable numerical results for proton-deuteron elastic scattering observables for energies above the deuteron breakup threshold , for the Paris potential. The calculations have been performed within the screening and renormalisation approach. The theoretical results are compared with experimental data of Sagara et al.
Fluorescence polarisation of 1,6-diphenyl-1,3,5-hexatriene was used to study the lymphocyte membrane in rheumatoid arthritis. The increase of polarisation value in the patients (n = 27) compared with healthy controls (n = 32) suggests a decrease of membrane fluidity. Moreover, erythrocyte sedimentation rate (ESR) and plasma fibrinogen concentrations were positively correlated with lymphocyte fl...
It has been shown by Simmons, Newsam & Willis (1995) (hereafter SNW95) that microlensing of stars can produce a distinctive and significant polarisation signature, even for lensed stars with no net unamplified polarisation. In this contribution, we use the model developed in SNW95 to simulate a series of realistic observations of microlensing events. We use these simulations to examine how much...
In this investigation, the effect of grain size on the corrosion behavior of 304L stainless steel has been studied. Samples with grain sizes of 0.5, 3 and 12 micrometers were fabricated through formation of strain-induced martensite by 80% cold rolling of the stainless steel sheets at -15 °C and its reversion to austenite during annealing at 900 °C for 1, 5 and 180 min. The corrosi...
We treat the old problem of the proton-neutron bound state (the deuteron). Using a new concept of incomplete (partial) annihilation process we derive a formula for the binding energy of the deuteron, which does not contain any new constant. Some implications of this new approach are discussed.
We report the measurement of charged hadron production at different pseudo-rapidity values in deuteron+gold as well as proton-proton collisions at √ sNN = 200GeV at RHIC. The nuclear modification factors RdAu and Rcp are used to investigate new behaviors in the deuteron+gold system as function of rapidity and the centrality of the collisions respectively.
The cross section asymmetry Σ in deuteron disintegration with linearly polarized light is considered in the framework of the Bethe-Salpeter formalism. Relativistic contributions to the asymmetry are investigated within the approximation, which takes into account the one-body part of the electromagnetic current operator and the dominant positive-energy partial amplitudes of the Bethe-Salpeter ve...
Recent progress is reviewed in four areas where new experimental data have been obtained: proton-proton bremsstrahlung, threshold pion production in proton-proton collisions, elastic electron-deuteron scattering and deuteron photodisintegration at several GeV photon energy. Relativistic effects are expected to be significant in these processes. High energy photodisintegration suggests that part...
