    "abstract": "We examine time reversal invariance in the beta-decays of 8B(2+) and 8Li(2+)\nto 8Be(2+) in detail, with particular attention to final state interactions of\nthe two alpha particles from the decay of 8Be, and of the electron (positron)\nwith the daughter nucleus. A R-matrix formulation is used, with the initial\nstate described by a shell model. The R-matrix parameters are obtained by\nfitting the alpha-\\alpha scattering phase shifts and allowed beta-decay rates.\nBecause the nuclear final state interaction effects on the time reversal test\ncome from second forbidden beta-decays, they are small and can be minimized by\na suitable choice of kinematic conditions. The e(+/-)-nucleus Coulomb\ninteraction induced T-violation effects depend on the first forbidden\noperators.",
