The ${}_{}{}^7{}_{}{}^{}\mathrm{Li}$ nucleus is studied in a cluster picture with elementary alpha and triton particles as constituents. The relation of this elementary cluster model to the microscopic resonating group model is investigated. Within this cluster model various measurable quantities such as root mean square radii, transition probabilities, electromagnetic moments, and form factors are calculated and compared with the experiment. While the agreement for the electric quantities is surprisingly good, there are deviations for the magnetic ones.
