Search for the Radiative Capture d+d->^4He+γReaction from the ddμMuonic Molecule State

Abstract

A search for the muon catalyzed fusion reaction dd --> ^4He +γin the ddμmuonic molecule was performed using the experimental μCF installation TRITON and NaI(Tl) detectors for γ-quanta. The high pressure target filled with deuterium at temperatures from 85 K to 800 K was exposed to the negative muon beam of the JINR phasotron to detect γ-quanta with energy 23.8 MeV. The first experimental estimation for the yield of the radiative deuteron capture from the ddμstate J=1 was obtained at the level n_γ\leq 2\times 10^{-5} per one fusion.
