[en] We have measured small angle correlations between light particles (p,d,t,α) at an energy of 140 for the ¹⁶O+²⁷Al and ¹⁸O+²⁷Al systems. The correlation functions were measured at a laboratory angle of 20 degrees with the Stony Brook LINAC. As for earlier work, the p-p and p-d results from both systems are well fit by a model which assumes statistical emission from an equilibrated compound nucleus. The d-α and α-α results from the two systems can be reproduced if a small amount of decaying excited ⁶Li or ⁸Be are included in the simulation. Finally, the relative two particle yields and deduced ⁸Be yield, which are very different for the two systems, will be compared to predictions based on statistical emission
