    "abstract": "We investigate the nonrelativistic reduction of the Bethe-Salpeter amplitude\nfor the deuteron electrodisintegration near threshold energies. To this end,\ntwo assumptions have been used in the calculations: 1) the static approximation\nand 2) the one iteration approximation. Within these assumptions it is possible\nto recover the nonrelativistic result including a systematic extension to\nrelativistic corrections. We find that the so-called pair current term can be\nconstructed from the $P$-wave contribution of the deuteron Bethe-Salpeter\namplitude. The form factor that enters into the calculation of the pair current\nis constrained by the manifestly gauge independent matrix elements.",
