    "abstract": "For some values of the constituent masses m_i, the hydrogen-like molecule\n(m_1^+,m_2^+,m_3^-,m_4^-) is stable with respect to spontaneous dissociation\ninto two neutral atoms, while none of its three-body subsystems such as\n(m_1^+,m_2^+,m_3^-) is stable. This occurs in particular in the neighbourhood\nof the (M^+,m^+,M^-,m^-) configuration with M/m=2, as for instance for the\nmolecule (p,d,\\bar{p},\\bar{d}) involving an antiproton and an antideuteron.",
