The gamma radiation in the interaction of 14.9-MeV neutrons with a natural lead sample is investigated by the total gamma radiation measurement technique (TGRM). Forty-nine prompt gamma lines and 8 delayed gamma lines, which come from (n,n{prime}{gamma}) and (n,2n{gamma}) reactions of {sup 206}Pb, {sup 207}Pb, and {sup 208}Pb, are identified, and their differential production cross sections at 55, 90, and 140 deg are determined. Six mixed gamma-ray peaks are separated, and the production data of the prompt and delayed components are given separately. The production cross sections of three isomeric states (1,013.7 keV, (13/2){sup +}, 5.5 ms in {sup 205m}Pb; 2,200.2 keV, 7{sup {minus}}, 124 {micro}s in {sup 206m}Pb; and 1,633.3 keV, (13/2){sup +}, 0.81s in {sup 207m}Pb) are accurately determined. They are in good agreement with some recent experimental and theoretical results. This is the most successful example of applying TGRM in an (n,x{gamma}) experimental study following after the aluminum study.
