Supermultiplet Symmetry in the ReactionH3+Be9Li6+He6,Li*6+He6

Abstract
The reactions Be9(t, Li6)He6 and Be9(t, Li*6)He6 have been measured at a bombarding energy of 23.5 MeV. The reaction products He6(ground state), Li6(ground state), and Li6(3.56 MeV) are members of a spin-isospin supermultiplet, and the observed differential cross sections are dominated by a symmetry expected from such considerations. Significant deviations from symmetry are, however, seen, especially in the isospin-multiplet channel.
