Direct measurements of the thermal ionospheric ion distribution function made from two sounding rockets launched into the expansive phase of an auroral substorm are discussed. Ion flows perpendicular (convective) and parallel to the geomagnetic field

In a study of galactic cosmic ray intensity variations it had been found that there are two distinct classes of transient intensity decrease, which have been called type I and type II. Type I events are flare-associated Forbush decreases. Type II eve

The time dependent worldwide distribution of atmospheric fast neutrons has been determined in balloon and aircraft measurements from 1964 to 1971. The 1- to 10-Mev neutron spectrum was measured with a phoswich detector employing seven channels of pul

We have calculated the global distribution of atmospheric neutrons and their products by a Monte Carlo simulation of nucleon transport in the internuclear cascade followed by neutron transport below 19 Mev. First, we present the results generated by

During solar particle events from 1968 to 1971 we observed increases in the fast neutron flux at high latitude and at 55- to 75-g/cm² atmospheric depth. The increases correlated with the variations in the solar proton fluxes; the neutron yield per i
