Continuity-Equation Constraint and the Non-Uniqueness of the Vector Potential Decompositions

  • Conference paper
Weak and Electromagnetic Interactions in Nuclei

Abstract

The use of the continuity-equation constraint (CEC) has proven highly useful in calculations of the deuteron photodisintegration [1,2], electric-type form factors in (e,e′) scattering [3,4], and even more complicated radiative muon capture [5]. It is motivated as an extension of the Siegert hypothesis: the nuclear impulse-approximation transition operator is via the continuity equation and by-parts integration transcribed in a form which mainly depends on the nuclear charge density for which the omitted meson exchange corrections are of order (υ/c)2. The terms which depend on the nuclear current MEC of order υ/c go as small corrections at low momentum transfers.
