The measurement method and results measuring of the stopping
power ratio of helium-3 and deuterium atoms for muons slowed down
in the D/3He mixture are presented. Measurements were performed
at four values of pure 3He gas target densities, ϕHe
= 0.0337, 0.0355, 0.0359, 0.0363 (normalized to the liquid
hydrogen density) and at a density 0.0585 of the D/3He mixture.
The experiment was carried out at PSI muon beam μE4 with the
momentum Pμ= 34.0 MeV/c. The measured value of the mean
stopping ratio S is 1.66±0.04.
