Preliminary studies for three experiments at Treiman-Yang criterion.

Nuclear reactions with three bodies in their final state may proceed through different reaction mechanisms. The Feynman graph technique has been widely used to describe such reactions. However, it is very difficult in general to select the graphs that dominate in given process. The Treiman-Yang criterion is one of the most powerful experimental tests for verifying the pole approximation prediction when describing a quasi-free reaction mechanism. We propose the theoretical study of the H²(B¹⁰, α Be⁷)n_s, H¹(B¹¹,α₁ α₂)α_s, He³(Be⁹, α₁α₂)α_s reactions at different energies. The preliminary study helps to check the existence of a QF channel by using the TY creterion. [ABSTRACT FROM AUTHOR]
