Abstract
The differential and integral range spectra of the hard component of cosmic rays in water and lead have been determined up to a thickness of 1500 g cm?2 of water, and 2800 g cm?2 of lead. The differential results indicate that there is no anomaly with an intensity greater than 5 per cent. in the differential momentum spectrum in the region below 4 BeV/c.
