Abstract

The ground bound states in the five-body muonic ions a b μe₂ (or (a b μe₂)^-), where (a, b) = (p, d, t), are considered for the first time. As follows from accurate numerical computations of these five-body ions they are similar to the negatively charged hydrogen ion H^- with a three-particle central quasi-nucleus a b μ (or (a b μ)⁺). These five-body ions play some role in the muon-catalyzed fusion of nuclear reaction in liquid deuterium and/or deuterium-tritium mixtures. We also discuss the bound states in the six-body a b c μe₂ quasi-molecules, where (a, b, c) = (p, d, t). These six-body, two-electron quasi-molecules are of great interest for muon-catalyzed nuclear fusion, since in liquid deuterium and/or deuterium-tritium mixture more than 99 % of all muon-catalyzed reactions of the (dd)- and (dt)-fusion occur in such six-body quasi-molecules: d d t μe₂, d d d μe₂ and d t t μe₂.
