The excitation function for the ${\mathrm{Al}}^{27}(d, \alpha p){\mathrm{Na}}^{24}$ reaction has been measured between 0 and 28.1 Mev. The external beam facilities of the Buenos Aires 71-in. synchrocyclotron were used together with the stacked-foil technique. Between 19 and 28.1 Mev present results are more precise than those previously obtained, showing that the maximum of the cross section is located at 24.25 Mev with a value of 51.4 mb.
