EXPERIMENTAL-STUDY OF SPIN EFFECTS IN THE RESONANT FORMATION OF MUONIC DEUTERIUM MOLECULES

The temperature dependences of the rates of formation of dd-mu-molecules from the two states of the hyperfine structure of the d-mu-atom and the transition rate between these two states have been measured in experiments with high density deuterium (phi approximately equals 1). A comparison of the results with measurements at a deuterium density phi = 0.02 indicates the possibility of a density effect in the formation of dd-mu-molecules from the upper spin state of the d-mu-atom.
