Abstract

The stability of m +1 m +2 m −3 m −4 Coulomb systems formed by particles of unit charge against dissociation is considered as a function of the particle mass. It is shown that, from the stability of the m +1 m +2 m −3 three-particle system, it follows that the m +1 m +2 m −3 m −4 four-particle system containing an additional particle of mass satisfying the condition m −4 ⩽ m −3 is stable. The results of calculations of the stability domain for m +1 m +2 m −3 systems asymmetric in particle masses are reported. The stability of 39 asymmetric exotic four-particle molecules and mesic molecules against dissociation is established.
