Abstrakt: We present the results of an experiment performed at PSI to investigate muon catalyzed fusion in pure deuterium gas of 5% density (LHD) at temperatures ranging from 28 K to 350 K. Using a new high pressure ionization chamber the reactions dd→ n+ 3He and dd → p+twere observed with 100% detection efficiency. The rates of dμdformation were measured with the absolute precision of 1% and the μdspin-flip rates with 0.5%. The temperature dependence of molecular formation and spin-flip rates display pronounced resonance structures. A preliminary fit based on the Vesman mechanism of resonant muonic molecule formation was carried out yielding a ddfusion rate of 3.5·108s-1and a hfs splitting energy $$\delta \varepsilon _{d\mu d} $$ of 24.3 meV, both in good agreement with the theory.
