Search for the Radiative Capture d+d->^4He+\gamma Reaction from the dd\mu Muonic Molecule State

摘要

A search for the muon catalyzed fusion reaction dd --> ^4He +\gamma in thedd\mu muonic molecule was performed using the experimental \mu CF installationTRITON and NaI(Tl) detectors for \gamma-quanta. The high pressure target filledwith deuterium at temperatures from 85 K to 800 K was exposed to the negativemuon beam of the JINR phasotron to detect \gamma-quanta with energy 23.8 MeV.The first experimental estimation for the yield of the radiative deuteroncapture from the dd\mu state J=1 was obtained at the level n_{\gamma}\leq2\times 10^{-5} per one fusion.
