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