Abstract
Formal expressions are derived for the multipole expansion of the structure
functions of a general polarization observable of exclusive
electrodisintegration of the deuteron using a longitudinally polarized beam
and/or an oriented target. This allows one to exhibit explicitly the
angular dependence of the structure functions by expanding them in terms of
the small rotation matrices
, whose coefficients are
given in terms of the electromagnetic multipole matrix elements.
Furthermore, explicit expressions for the coefficients of the angular
distributions of the differential cross-section
including multipoles up to
are listed in tabular form.
