Electron tunneling measurements have been carried out on granular and crystalline aluminum. The Eliashberg gap equation has been inverted and α2 F and Μ* are given. Some problems such as anomalous effects in the junction behavior, and deviation from the BCS density of states at the gap edge in the granular case, and the data at low energies are qualitatively discussed.
