Abstract
Doppler broadening of the γ-lines of the secondary ion 13C*, produced in the 16O(n, αγ)13C reaction induced by neutrons interacting with the beryllium oxide target, is calculated within the framework of the LSS model for the stopping power of the low energy ions. The 16O(n, αγ)13C cross-sections are calculated by the quark-level nuclear reactions model CHIPS. It is shown that for not too short and not too long lifetimes of the excited γ-levels the slowing down of the radioactive ions defines shapes of the measured γ-lines.
