MEASUREMENTS OF NEGATIVE $mu$-MESONS POLARIZATION IN MESIC ATOMS OF CARBON, OXYGEN, MAGNESIUM, SULFUR, ZINC, CADMIUM, AND LEAD

Technical Report ·
OSTI ID:4321594
The angular distributions of electrons from mu - meson decay in mesic atoms of C, O, Mg, S, Zn, Cd, and Pb were measured by means of scintillation counters. The mu /sup -/meson polarization was determined on the basis of measurements. In mesic atoms of Mg, Zn, Cd, and Pb polarization equals to (19 plus or minus 7) %; for C, O, and S mesic atoms polarization equals (14 plus or minus 4) %. The mu /sup -/ meson depolarization in matter with zero nuclear spins is explained mainly by spin-orbital interaction in the process of mesic atom production; depolarization is partially connected also with interaction of the magnetic field of the electron atom shell on mu /sup -/ meson during its life time on K orbit.
