Abstract

Production of isotopes by cosmic rays in the Earth’s atmosphere plays a key role in many studies in solar physics, geophysics, archeology and other fields. For those purposes, precise quantitative modeling of their production is crucial, and high-resolution altitudinal profiles of production rates are in high demand. Here we present detailed and consistent yield functions of isotopes 7Be, 10Be, 14C, 22Na and 36Cl produced by energetic particles in the atmosphere. Comparison of reconstructions of the 10Be deposition flux in 1951-2013 and around 775 AD with ice core measurements is shown for illustration of application of our yield functions.
