The discrete {gamma} radiation in the interaction of 14.9-MeV neutrons and a natural silicon sample is investigated with a total {gamma}-radiation measurement (TGRM) technique. Fifty prompt {gamma} lines, one delayed {gamma} line, and seven final nuclei are identified. Forty-one possible transitions are designated. Differential production cross sections of 40 {gamma} lines at 40 deg., 55 deg., 90 deg., 125 deg., and 140 deg. are determined. Using relative differential production cross sections, accurate integral isotopic cross sections of the {sup 28}Si(n,p){sup 28}Al reaction are determined, and partial integral isotopic cross sections of the {sup 28}Si(n,n'){sup 28}Si, {sup 28}Si(n,{alpha}){sup 25}Mg, {sup 29}Si(n,n'){sup 29}Si, and {sup 30}Si(n,n'){sup 30}Si reaction channels are also estimated. The present results are in good agreement with some recent experimental and evaluated results.
