| Popis: | In a series of balloon flights, at 4.6 bv geomagnetic cutoff rigidity (corresponding to the geomagnetic latitudes of about 46° in northern Italy and about 42° in southern New Mexico, United States), with a light-weight neutron detector, the flux of the cosmic ray neutrons in the atmosphere has been investigated in the energy range from thermal to about 20 Mev. The energy spectrum proposed by Newkirk has been found to be in agreement with the experimental results. Values of the integrated neutron flux at different atmospheric depths are given; by extrapolating to zero pressure, the leakage flux has been determined as (0.45±0.07) neutrons cm−2 sec−1. |
