*** *DIS on a Polarized Spin-1 Target with Spectator Tagging

*We discuss the process of deep-inelastic electron scattering (DIS) on 
the polarized deuteron
with detection of a nucleon in the nuclear fragmentation region 
("spectator tagging"). We
cover (a) the general structure of the semi-inclusive DIS cross section 
on a spin-1 target;
(b) the tagged structure functions in the impulse approximation, where 
deuteron structure
is described by the NN light-front wave function; (c) the extraction of 
free neutron structure
through on-shell extrapolation in the recoil proton momentum. As an 
application we consider
the extraction of the neutron structure function F_2n and spin structure 
function g_1n through
electron scattering on the (un)polarized deuteron with proton tagging 
and on-shell extrapolation.
Such measurements would be possible at an Electron-Ion Collider (EIC) 
with polarized deuteron
beams and forward proton detectors.  We comment on the influence of 
final-state interactions
on these observables in kinematics at the EIC.
