The domain of stability of unnatural parity states of three unit charges
Jean-Marc Richard
We investigate the domain of masses for which a state with total orbital momentum L=1 and unnatural parity exists for the Coulomb systems .
Mass-symmetry breaking in three-body ions
V. I. Korobov, J. -M. Richard
The ground-state energy of three-body ions evolves when the like-charge constituents are given different masses. The comparison of with the aver…
Critically-bound four-body molecules
Jean-Marc Richard
The molecule, with a proton, a deuteron and their antiparticles, is stable againt spontaneous dissociation, but none of its three-body subsystems are stable…
Borromean molecules
Jean-Marc Richard
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…
