• The effect of the diffuse nuclear potential on the penetration of the potential barrier is examined using a simplified model. The transmission coefficient for slow neutrons is treated in an exact way employing an exponential diffuse potential and is found to be larger by a factor 2 than in the usual calculation(§ 2). The Coulomb penetrability is investigated on the basis of the W-K-B method, and the diffuseness makes the penetration factor much larger than that obtained in the conventional calculation(§ 3). An application to the evaporation process is developed(§ 4)and the energy spectrum of α-particles from the ^<27>Al(n;α)^<24>Na reaction is found to be explained by the corrected penetrability in a satisfactory way.
