A nuclear-like bound state with a binding energy close to the tritium binding energy and with quantum numbers I(Jp) = 1/2(1/2-) was obtained for the p̄pn system without specification of NN and NN potentials by using the Faddeev equations. A search for the predicted quasi-tritium state was concentrated in experiments on the annihilation of stopped antiprotons in deuterium with the emission of monoenergetic γ quanta that correspond to radiation transitions from the states of the pd atom to the examined quasi-tritium state with a relative intensity ≳ 10–3.
