Abstract

A complete investigation has been made of the angular distribution (over various zeniths and azimuths) of the hard component of cosmic rays at the Gulmarg High Altitude Research Observatory (Geomagnetic latitude 24.7° N). The azimuth distribution is found to agree closely with an energy law E −1.89 dE for all the zenith angles. The zenithal distribution is found to be a cosine power law in which the index « n » varies regularly with azimuth. A sinusoidal dependence of « n » on azimuth has also been obtained by the method of least squares.
