The total fusion cross section for the system /sup 15/N+/sup 27/Al has been measured over an energy range 27 MeV< or =E/sub lab/< or =70 MeV by detection of the fusion-evaporation residues. In addition elastic scattering was measured at six energies and fitted by optical model calculations. The fusion cross section for the system saturates at 1150 +- 50 mb. The data can be well described by the model of Glas and Mosel, using a reasonable set of parameters. The model of Horn and Ferguson also describes the data well if an appropriate charge radius is used. Comparison is made between these results and the fusion cross sections for /sup 16/O+/sup 26/Mg and /sup 18/O+/sup 24/Mg, which lead to the same compound nucleus. The results for /sup 15/N+/sup 27/Al are quite similar to those for /sup 18/O+/sup 24/Mg, and the differences between the fusion cross sections for these two systems and those for /sup 16/O+/sup 26/Mg may be evidence for an entrance channel effect.
