Calculation of the relativistic charge form factor of the deuteron directly from experimental n-p phase shifts

Abstract

A new relativistic integral representation in terms of experimental n-p phase shifts alone for the charge form factor of the deutron G C d( q 2) is used. The results of the numerical calculation of G C d (q 2) are presented for the s-wave deuteron in the interval of the four-momentum transfers squared 0 ⩽ q 2 ⩽ 30 fm −2. The change of sign in the experimental 3S 1-phase shifts leads to a dip and a prominent secondary maximum in G C d (q 2) . The calculated value of the deuteron charge root-mean-square radius RMSR is equal to the experimental one.
