<font size="2"><b>DIS on a polarized spin-1 target with
spectator tagging</b></font><br>
<font size="2">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. </font><br>
