ResumoDeep-inelastic electron scattering from $^{3}\mathrm{He}$ at momentum transfers $1<~{Q}^{2}<~4$ (GeV/${\mathit{c})}^{2}$ is successfully described in a quark-cluster model of the nucleus. The quark-cluster probabilities and Fermi motion are obtained from a nuclear wave function consistent with low-energy data. A nucleon-bag (three-quark-cluster) radius of 0.45 fm provides an optimal description of the data. It fixes the geometrical probabilities at 0.83, 0.16, and 0.01 for three-, six-, and nine-quark clusters, respectively.
