The ratio of excitation energies E{sub x} and neutron separation energy S{sub n} for neutron resonances of {sup 16}O+n are observed to be ratios of simple integers. Similar analyses are made for the resonances of light target nuclei, {sup 3}He, {sup 6,7}Li, {sup 8,9}Be, {sup 10,11}B, {sup 12,13}C, {sup 14,15}N, {sup 16,18}O showing that E{sub x}/S{sub n}=4/3 or 5/3 are values that appear in many nuclei. A statistical test shows that these integer ratios do not exist by accident but that they have a physical origin. A classical model of neutron resonance reaction is developed relating these integer ratios, based on the breathing of the compound nucleus that is coherent with the incident neutron wave. Origin of integer ratios among E{sub x}, S{sub n} of different nuclei are discussed based on a constant G value and integer splitting for many nuclei.
