| Description/Abstract | The cosmic-ray neutron energy spectrum in the equilibrium region of the atmosphere was measured with several different calibrated detectors from thermal energies to about 1 Bev at 44 deg north magnetic latitude and up to 40,000 feet. By combination of the data from these measurements with those from other experiments, a complete differential energy spectrum is obtained which shows the characteristic maximum near thermal energies and a roughly 1/E variation up to about 100 kev. The presence of a second maximum in the spectrum near 1 Mev is attributed to the evaporation neutrons from stars, and above this energy up to 800 Mev the spectrum falls off as E/sup -1.4/. (auth) |
