The charge form factor of ${}_{}{}^7{}_{}{}^{}\mathrm{Li}$ is calculated with a semimicroscopic method in which the Pauli principle is taken fully into account but the intercluster relative motion is parametrized in a way guided by cluster-model considerations. The results show that there is a large degree of $t+\alpha$ clustering in the ground state of ${}_{}{}^7{}_{}{}^{}\mathrm{Li}$ and that specific distortion effects are fairly important in this system.
