Parameterization of the Deuteron form Factors and the Tensor Polarizations

Abstract

For parameterization deuteron wave functions as a product of exponential function rn by the sum of the exponential terms Ai*exp(-ai*r2) are received analytical forms for spherical S0 and quadrupole S2 deuteron form factors. The modern status of experimental data for deuteron tensor polarizations t20 and t21 is analysed. On received analytical forms for spherical and quadrupole form factors calculated deuteron tensor polarization t2i. The result t20(p) in wide area of momentas for NijmI, NijmII, Nijm93, Reid93 and Argonne v18 potentials agreed well with the literature results for other potential nucleon-nucleon models, and with experimental data of world collaborations (Bates, BLAST, JLab, NIKHEF, VEPP-3, Saclay) and reviews (Boden, Garcon, Abbott). Reduced quantity tensor polarization t20R it is compared to experimental data. The obtained results will allow studying the deuteron electromagnetic structure, its form-factors, differential cross section of double scattering in more detail in future, and also for calculations the theoretical values of spin observables in dp- scattering.
