Cosmic-ray atmospheric cutoff energies of polar neutron monitors [PDF]
Advances in Space Research, 2022 The atmospheric cutoff, similarly to the geomagnetic cutoff, is the lower energy limit for cosmic ray particles that can reach a given location on the ground and be registered by a detector there, e.g., by a neutron monitor.

Properties of the thermal radiation emitted by neutron stars (NSs) are determined by thin plasma layers (atmospheres) at their surfaces. The NS atmospheres are very different from those of usual stars due to the immense gravity and huge magnetic fields. Current models of hydrogen NS atmospheres show that the spectra deviate substantially from blackbody

Nucleosynthesis in neutron star atmospheres
Astrophysics and Space Science, 1969The composition of neutron star atmospheres is calculated as a function of time including effects of diffusion, cooling and thermonuclear reactions. A seven-component nuclear reaction network with includes He4, C12, O16, Ne20, Mg24, Si28 and Fe56 is utilized.

Measurements of the atmospheric neutron leakage rate
Journal of Geophysical Research, 1973The atmospheric neutron leakage rate in the energy range from 0.01 to 10,000,000 eV has been measured as a function of latitude, altitude, and time with a neutron detector on board the Ogo 6 satellite. The latitude dependence of the neutron leakage is in reasonable agreement with that predicted by Lingenfelter (1963) and Light et al.

Atmospheric neutron flux measurements
Journal of Geophysical Research, 1964The energetic neutron flux at atmospheric depths from 160 to 300 g/cm−2 has been measured over latitudes extending from the equator to 55°N geomagnetic. Comparison of data with previous measurements indicates that at the time of these measurements the neutron spectrum was steeper than that determined by Hess et al. for neutrons of E > 60 Mev but was of

Proton deceleration in a neutron star atmosphere
AIP Conference Proceedings, 1982The energy loss rate of fast protons in a strongly magnetized electron gas has been calculated using the Fokker‐Planck equation to describe the dominant effect of small‐angle Coulomb scattering. Stopping lengths or order 1 gm cm−2 are obtained for 30 MeV protons and the possibility of maser action at the gyrofrequency is indicated.
