    "abstract": "The ground-state energy of three-body ions $(M^+,M^+,m^-)$ evolves when the\nlike-charge constituents are given different masses. The comparison of\n$(m_1^+,m_2^+,m^-)$ with the average of $(m_1^+,m_1^+,m^-)$ and\n$(m_2^+,m_2^+,m^-)$ reveals a competition between the symmetric term and the\nantisymmetric one. The former dominates in the Born--Oppenheimer regime such as\nthe (p,t,e) case, while the latter wins for H$^-$-like systems with two\nnegative light particles surrounding a heavy nucleus. A comparison is also made\nwith the case of baryons in simple quark models with flavour independence.",
