Abstract
We consider a composite spin-half particle moving in spatially varying scalar and vector fields. The vector field is assumed to couple to a conserved charge, but no assumption is made about either the structure of the composite or its coupling to the scalar field. A general form for the piece of the spin-orbit interaction of the composite with the scalar and vector fields which is first order in momentum transfer Q a nd second order in the fields is derived.
