摘要：

Two experiments with low-energy muons are described: the determination of the stopping power of C, Si, Ti and Au for muons at energies down to 2 keV and the measurement of the diffusion times for P mu and d mu atoms in low-pressure (0.25-12 hPa) hydrogen gas. A pronounced Parkas effect was found for muons at the Bragg peak (about 10 keV): the stopping power for mu(-) in C, e.g., is about 30% lower than that for mu(+). The mean kinetic energy of p mu atoms at the end of the cascade in 1 hPa hydrogen gas was determined to be (2.6+/-0.6) eV (preliminary value).
