Measurement of the spin and temperature dependence of ddµ molecule formation rate in solid and liquid deuterium

The ddµ molecule formation rate is experimentally measured for the two hyperfine states of the dµ-atom in the temperature range of 5–30 K. Results are consistent with a preliminary measurement by the TRIUMF group and contradict theoretical predictions. The work has been performed on the JINR phasotron (Dubna).

Temperature and density dependence of μ-catalysis cycling rate in dense D/T and H/D/T gas mixtures

AbstractMuon catalyzed dt fusion in dense D/T and H/D/T gas mixtures of hydrogen isotopes is studied by the MCF collaboration at JINR. The measurements were carried out with a high pressure target at the JINR phasotron in the temperature range 300-800 K at mixture densities

Investigation of the parameters of muon-catalyzed fusion in double D/T mixture at high temperature and density

Preliminary data are first presented for the measurements of effective parameters of MCF processes in dense D/T mixtures obtained by a novel method. Results are compared with the ones obtained by the “standard” method.

First measurements of dtμ cycle characteristics in liquid H/D/T mixture

A vast program of the experimental investigation of muon-catalyzed dt fusion was performed on the Joint Institute for Nuclear Research phasotron. Parameters of the dt cycle were obtained in a wide range of the D/T mixture conditions: temperatures of 20–800 K, densities of 0.2–1.2 of the liquid hydrogen density (LHD), and tritium concentrations of 15–86%. In this paper, the results obtained are summarized.

Experimental investigation of muon-catalyzed t + t fusion

The original experimental method for further µCF study in double, D/T, and triple, H/D/T, mixtures of high density is considered. This method is the base of the international project sponsored by the ISTC.

Experimental search for the radiative capture reaction d + d → 4He + γ from the ddμ muonic molecule state J = 1

An installation is made to investigate the temperature and spin dependence of the ddu “meso”-molecular formation rate in deuterium in solid, liquid and gaseous phases. It is composed of a target cooled with helium of a volume equal to 280 cm3 and target thermostabilization and gas-handling systems. The temperature of the target in the range 5-40 K can be fixed with an accuracy of 0.2 K.
