Pitch angle distribution of photoelectrons measured on the Cosmos 348 satellite
Abstract
The photoelectron pitch angle distributions measured on the Cosmos 348 satellite are discussed in terms of their variation with energy and altitude. The distribution of 30 eV photoelectrons is characterized by a deep minimum for angles 75 deg-105 deg with respect to the geomagnetic field, and are independent of altitude. The minimum disappears rapidly with increasing photoelectron energy and the distribution becomes isotropic. Measurements at higher altitudes (above 500 km) show that the upgoing 60 eV photoelectron flux is much larger than the downward flux.
