The Treiman-Yang Criterion is a model-independent experimental test for the dominance of the Quasi-Free Breakup (pole) mechanism of a reaction. The test involves measuring the cross-section for non-coplanar configurations and checking the invariance of the reaction amplitude for different Treiman-Yang angles. An experiment was performed at Laboratori Nazionali del Sud in June 2016 to verify the criterion for the $d({}^{10}B$, ${}^{7}Be \alpha)n$ reaction. Here, the criterion is described and some results from the experiment are shown.
