[email protected] The authors are indebted to their colleagues, Robert S. Norris and David Schwarzbach, for close reading of drafts of this paper, and to Richard K. Wallace, William J. Quirk, Ray E. Kidder, Richard L. Garwin, and Theodore B. Taylor for sharing their expert views on the relative technical utility of hydronuclear and other low-yield nuclear tests. They are of course in no way responsible for the conclusions reached, which may be at variance in some respects with their own views. These views, we hasten to add, were themselves divergent on a number of points. NRDC's work on nuclear test ban issues is supported by grants from the Winston Foundation, the Ploughshares Fund, the Carnegie Corporation of New York, the W. Alton Jones Foundation, and the John D. and Catherine T. MacArthur Foundation. A. Gun-assembly Pure Fission Designs 3 B. "Solid-pack" Implosion Type Pure Fission Designs. 4 C.
