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.

Simple semiempirical formulas for K-shell photoionization cross sections for gamma rays have been obtained based on the experimental results of coincidence and direct measurements. The data used cover the energy region from 145.4 to 1332.5 keV and atomic number Z from 29 to 90. Results obtained from these formulas agree fairly well with Scofield's theoretical results.
