Abstract
A Geiger counter telescope has been employed to study μ-mesons incident at large zenith angles. The counters were hodoscoped in pairs enabling the direction and angle of incidence of the particles to be determined. The intensity has been analyzed as a function of arrival time but no significant variation has been found either in solar time or sidereal time. However, a variation in solar time has been noted on analysis of extensive air showers measured concurrently. The angular variation of intensity has been studied and absolute rates obtained; these rates have been compared with those of an earlier determination showing excellent agreement. Some evidence has been obtained of a directional anisotropy in the μ-meson flux as measured at the apparatus.
