摘要: We consider the influence of capture epithermal neutrons on nucleosynthesis in asymptotic giant branch stars (the Petrov-Shlyakhter effect). show that can be captured by nitrogen through hitherto unanalyzed channel 14N(n, α)11B. Since proton concentration partial mixing zone is low, this process results an appreciable boron concentration. This brought to stellar surface peculiar processes. analyze as a function assumed parameters for zone.
