Abstract

For some values of the constituent masses m_i, the hydrogen-like molecule (m₁⁺,m₂⁺,m₃^-,m₄^-) is stable with respect to spontaneous dissociation into two neutral atoms, while none of its three-body subsystems such as (m₁⁺,m₂⁺,m₃^-) is stable. This occurs in particular in the neighbourhood of the (M⁺,m⁺,M^-,m^-) configuration with M/m=2, as for instance for the molecule (p,d,p,d) involving an antiproton and an antideuteron.
