Abstract
Data from the DECOR coordinate detector on the integrated intensity of muons that have a threshold energy of 1.2 to 2 GeV are analyzed over the zenith-angle interval 60°–90°. Experimental results in these intervals of zenith angles and threshold energies were obtained for the first time. In the interval θ ≤ 80°, the integrated intensity at E min = 1.5 GeV as a function of the cosine of the zenith angle is described by a power-law function characterized by an exponent value of n = 1.884 ± 0.005, which is close to the value obtained in earlier experiments.
