ATMOSPHERIC NEUTRON FLUX MEASUREMENTS,
Abstract
A measurement of the energetic neutron flux at atmospheric depths from l60 gm cm-2 to 300 gm cm-2 has been carried out over latitudes extending from the equator to 55 degrees N geomagnetic. Comparison of data with previous meas urements indicate that at the time of these measurements the neutron spectrum is steeper than that determined by Hess et al (1959) for neutrons of E greater than 60 Mev but is of the same form for E less than 10 Mev. An anomalous increase in the flux of neutrons of E greater than 60 Mev was detected on 21 July 1962 over a region from 50 degrees to 55 degrees N geomagnetic. The increase is possibly attributable to a dumping of protons temporarily trapped in the slot between the inner and outer Van Allen zones. (Author)
