We study a low-energy effective field theory (EFT) describing the NN system in which all exchanged particles are integrated out. We show that fitting the residue of the S1 amplitude at the deuteron pole, rather than the S1 effective range, dramatically improves the convergence of deuteron observables in this theory. Reproducing the residue ensures that the tail of the deuteron wave function, wh...

Relativistic formulae for the deuteron electromagnetic form factors are calculated in the impulse approximation retaining terms to all orders in Q2/M2 z wc>2. The formulae are given as double integrals over the deuteron wave functions in momentum space, and hence can be evaluated for any deuteron model. We evaluate these formulae numerically for 9 different deuteron models: Reid soft core, two ...

A modified version of the Faddeev three-body equation to accommodate the Coulomb interaction, which was used in the study of three-nucleon bound states, is applied to the proton-deuteron scattering problem at energies below the three-body breakup threshold. A formal derivation of the equation in a time-independent scattering theory is given. Numerical results for phase shift parameters are pres...

Abstract We present a perturbative approach to solving the three-nucleon continuum Faddeev equation. This is particularly well suited dealing with variable strengths of contact terms in chiral force. use examples observables elastic nucleon-deuteron scattering as deuteron breakup reaction demonstrate high precision proposed procedure and its capability reproduce exact results. A significant red...

The molecular-beam magnetic-resonance method has been applied to study the radiofrequency spectra of the molecules D2 and HD, in the state J=1.All the measurements were made in applied magnetic fields large enough to decouple the angular momentum vectors concerned. The spectrum of D2 for the transitions mq —~1 consists of six lines as in H2. The HD spectrum consists of two sets, one of nine lin...

The effective interaction potential for charged particles is calculated in the deuterium plasma formed in the surface region of the palladium cathode in the electrolysis of heavy water. It is shown that the Coulomb potential is overscreened producing, at certain distances, an attractive potential between deuterium nuclei pairs and also between the deuterium nuclei and the surface atoms. This be...

MEASUREMENT OF THE SPIN STRUCTURE FUNCTION G1 OF THE DEUTERON AND ITS MOMENTS AT LOW Q2 Krishna P. Adhikari Old Dominion University, 2014 Director: Dr. Sebastian E. Kuhn Double polarization cross section differences (∆σ‖) for proton and deuteron targets have been measured in the EG4 experiment using the CLAS detector at Jefferson Lab. Longitudinally polarized electron beams at relatively low en...

The empirical value of the real part of the pion-deuteron scattering length can be well understood in terms of the dominant isovector πN -double scattering contribution. We calculate in chiral perturbation theory all one-pion loop corrections to this double scattering term which in the case of πN -scattering close the gap between the current-algebra prediction and the empirical value of the iso...
