Deuteron tensor polarization component T20(Q2) as a crucial test for deuteron wave functions
Abstract
The deuteron tensor polarization component T20(Q2) is calculated by relativistic Hamiltonian dynamics approach. It is shown that in the range of momentum transfers available in to-day experiments, relativistic effects, meson exchange currents and the choice of nucleon electromagnetic form factors almost do not influence the value of T20(Q2). At the same time, this value depends strongly on the actual form of the deuteron wave function, that is on the model of NN-interaction in deuteron. So the existing data for T20(Q2) provide a crucial test for deuteron wave functions.
