Integral Intensity of Cosmic Ray Muons Measured at a Low Latitude Station

61-62Integral intensity of vertical cosmic ray muons has been experimentally obtained at Ahmedabad (geomag. lat. 13°N; cut-off 16 GeV/c). Double coincidence rates were taken with different thicknesses of lead absorber to obtain integral intensities corresponding to different minimum momenta. These coincidence rates were corrected for chance coincidences. Integral intensities of muons for four values of minimum momenta (320, 495, 603 and 715 MeV/c) are obtained with a statistical accuracy of better than 0'5%. The results obtained are in agreement with those of earlier workers
