Polarization of underground cosmic mu /sup +/ mesons was investigated for a mean (with respect to the angular distribution) minimum momentum of 2.3 Bev/ c. The polarization was determined on the basis of asymmetry in the angular distribution of positrons emitted by decaying mu /sup +/ mesons in a copper absorber. 16290 decay events without a field and 14920 events with a depolarizing magnetic field of 80 gauss were observed. The polarization value is P = 0.25 plus or minus 0.03. The exponent in the pi -meson production spectrum was determined. (auth)
