Structure function of bound nucleons

Guided by the recent deep-inelastic $\mu A$ ($A=\mathrm{F}\mathrm{e},\mathrm{D}$) scattering data, we present a simple parametrization of the structure functions of nucleons bound in nuclei. The nuclear binding is represented by the effective mass of nucleons; the large-momentum tail of nuclear wave function is also included. A good fit to the data in the whole range of the scaling variable $x$ is obtained.
