摘要：
The isotope O-16 is one of the most abundant light isotopes, and therefore the process O-16(n,?)O-17 reaction plays a critical role in stellar nucleosynthesis. Reaction cross-sections and rates for neutron capture by O-16 at astrophysical energies have been calculated with special attention to low-lying, narrow resonances while implementing R-matrix formalism during integration.
