Abstract

For some values of the constituent masses m i , the hydrogen-like molecule (m 1 + , m 2 + , m 3 , m 4 ) is stable with respect to spontaneous dissociation into two neutral atoms, while none of its three-body subsystems such as (m 1 + , m 2 + , m 3 ) 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, \( \overline p \), \( \overline d \)) involving an antiproton and an antideuteron.
