Chemical behaviour of helium muonide just after muon catalyzed fusion

  • K. Yoshihara

Chemical behaviour of a helium muonide atom /Heμo/ can be understood on the analogy of its hydrogen homologues, muonium /Mu/, deuterium /Do/ and tritium /To/. In muon catalyzed fusion /μCF/, a small fraction of negative muon in the fusion cycle sticks to helium to give proton-like Heμ+ which easily picks up one electron forming Heμo. The energy of Heμ+ at birth is about 3.5 MeV being in a similar situation to the case of a hot tritium atom produced by /n, p/ or /n, α/ reaction. The reaction cross section and rate of Heμo reactions are estimated.
