The gamma-quantum yield from nuclear fusion reactions resulting from different spin states of the muonic molecules 𝑝𝑡𝜇 and 𝑝𝑑𝜇 has been measured. The muon sticking coefficient in the channel of the pt-fusion with a single gamma-quantum yield is experimentally determined. The fusion reaction channels with the yield of the double gamma-quanta 𝑝𝑡𝜇 → 4He𝜇 + 𝛾 + 𝛾, 𝑝𝑑𝜇 → 3He𝜇 + 𝛾 + 𝛾 are observed for the first time.

 

The observation of a single gamma-quantum in the fusion reaction channel 𝑝𝑡𝜇 → 4He𝜇 + 𝛾 agrees with the previous study. The research has been carried out at the Triton facility at DLNP (JINR) using a specially designed liquid-tritium target.
