    "abstract": "The determination of the spin distribution functions for the neutron requires\nan understanding of the changes induced by a nuclear medium. We present the\nfirst estimates of the changes induced in the spin-dependent, valence parton\ndistributions of the proton and neutron bound in $^3$He and $^6$Li. For $^3$He\nthe result is quite reassuring, in that the off-shell correction to $g_{1n}$ is\nvery small. On the other hand, in $^6$Li the corrections to the spin\ndistributions in the bound proton are sufficiently large that they should be\ntaken into account if one aims for a precision of better than 10%. We provide a\nsimple parametrization of the off-shell changes in the valence spin\ndistributions of $^3$He and $^6$Li, which can be used with any conventional\nestimate of nuclear binding and Fermi motion corrections.",
