Abstract

The μ-meson momentum spectrum near sea level in 57° N geomagnetic latitude has been measured for strictly defined angles of collection near the vertical direction. Results are given, covering the momentum range 5 × 108eV/C<p<2 × 1010 eV/C, which are based on the measurement of about 60 000 trajectories.
