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.
