Title: Measurement of the Q 2 Dependence of the Deuteron Spin Structure Function g 1 and its Moments at Low Q 2 with CLAS

We measured the $$g_{1}$$ spin structure function of the deuteron at low $$Q^{2}$$, where QCD can be approximated with chiral perturbation theory ($$\chi PT$$). The data cover the resonance region, up to an invariant mass of $$W\approx1.9$$ GeV. The generalized GDH sum, the moment $$\Gamma_{1}^{d}$$ and the spin polarizability $$\gamma_{0}^{d}$$ are precisely determined down to a minimum $Q^2$ of 0.02 GeV$^2$ for the first time, about 2.5 times lower than that of previous data. We compare them to several $$\chi PT$$ calculations and models. In conclusion, these results are the first in a program of benchmark measurements of polarization observables in the $$\chi PT$$ domain.
