An overview is given of some recent and planned experiments which have or will substantially increase our knowledge of the electromagnetic properties of the few body systems. Specific examples include the proton and neutron elastic form factors, the deuteron elastic form factors, deuteron threshold electro-disintigration and quasi-elastic scattering, deuteron photodisintigration, and finally me...

The excited-state deuteron transfer (ESDT) of deuterated 7-hydroxyquinoline (7DQ) along a heterogeneous hydrogen (H)-bonded chain composed of two deuterated alcohol (ROD) molecules having different acidities, as a model system of a proton wire consisting of diverse amino acids, has been investigated. To understand dynamic differences between deuteron transfer and proton transfer, solvent-invent...

Relativistic Calculation of Structure Functions b 1,2 (x) of the Deuteron. Abstract The structure functions b D 1,2 (x) of the deuteron are studied within covariant approach. It is shown that usual nonrelativistic convolution model result in incorrect behavior of this structure functions at small x and violates the exact sum rules. Realistic calculations are carried out with the Bethe-Salpeter ...

We find the leading order result for the anapole form factor of the deuteron using effective field theory. The momentum dependence of the anapole form factor is different from that of the matrix element of the strange currents in the deuteron, which may provide a way for disentangling these two competing effects when analyzing parity violating electron-deuteron scattering experiments. We give c...

The complex Kohn variational principle and the (correlated) hyperspherical harmonics method are applied to study the proton–deuteron elastic scattering at energies above the deuteron breakup threshold. Results for the elastic cross section and various elastic polarization observables have been obtained by fully taking into account the long–range effect of the Coulomb interaction and using a rea...

The deuteron form factors are calculated in the framework of the relativistic nucleon-meson dynamics. The relativistic effects change considerably the Sand D-waves of the deuteron, result in the dominating extra component in the deuteron wave function and generate the contact interaction between the nucleon, mesons and photon. The prediction for the polarization observable t20 is in good agreem...

We assume that due to their small binding energy, deuterons from the midrapidity region cannot survive inside fireballs created in ultrarelativistic nuclear collisions. All observed deuterons are thus expected to be created from a neutron proton pair at freeze-out by coalescence. This coalescence process involves small relative momenta and is thus a non-relativistic phenomenon. Switching to cen...

Deuteron implantation experiments on Ti and Pd foils have been made for the examination of the “cold” deuteron fusion reaction. In the center of a target chamber fitted to a 300 keV deuteron accelerator, a Ti or Pd foil sample was set to face toward 3 nsec pulsed deuteron beams collimated with a 3 mm diameter aperture. A Si-SSD was placed behind the foil to detect high energy charged particles ...

We study the effect of the neutrino magnetic moment on the neutrino-deuteron breakup reaction, using a method called the standard nuclear physics approach, which has already been well tested for several electroweak processes involving the deuteron.
