Proving DRACO will deliver
The United States is now closer than it has been in over five decades to launching the first nuclear thermal rocket into space, thanks to DRACO—the Demonstration Rocket for Agile Cislunar Orbit.

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') and (n,2n) reactions of 206Pb, 207Pb, and 208Pb, 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 (1013.7 keV, (13/2)+, 5.5 ms in 205mPb; 2200.2 keV, 7-, 124s in 206mPb; and 1633.3 keV, (13/2)+, 0.81s in 207mPb) 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) experimental study following after the aluminum study.
