n investigation on neutron induced reactions on stable CNO isotopes

he neutron induced reactions on stable Carbon, Nitrogen, and Oxygen isotopes are investigated by using the Talys1.4 toolkit with the default parameters. The neutron incident energy covers a range from 0.20 MeV to 85.00 MeV. For 12C and 14N, the Talys1.4 results agree with the experimental data, while the parameters should be adjusted for 16O. Some En windows are found by comparing the main channels of n + C/N/O reactions, which induce element change. In these En windows, a specific element is activated to a different one while leaving the other element atoms unchanged. The results will facilitate the research of doping effects in organic materials by using neutron activation technique.
