Abstract

The yield of gamma-quanta from nuclear fusion reactions proceeding from various spin states of muonic molecules ptμ and pdμ has been measured. The work was performed on the “Triton” facility at DLNP JINR using a specially designed liquid-tritium target. For the first time, channels of the fusion reaction with the yield of double γ-quanta were observed: ptμ → 4Heμ + γ + γ, pdμ → 3Heμ + γ + γ. The data obtained for the yield of single γ-quanta in the channel of the fusion reaction ptμ → 4Heμ + γ is consistent with earlier research. The partial coefficient of sticking of a muon to a helium nucleus was determined experimentally in a channel of pt- and pd-fusion reactions with the yield of single γ-quantum.
