Comments on U.S. nuclear export controls on China
As trade negotiations are in the works between the United States and China, Washington, D.C., has the advantage in semiconductors but nuclear power is a different story, according to a June 9 article in the Hong Kong–based South China Morning Post.

The use of the statistical properties of nuclear resonances to calculate fission-product poisoning in the intermediate energy range is described. On the basis of the available theoretical and experimental information, estimates of the average fission-product cross section as a function of energy are given for the energy range 102 to 106 electron volts. Comparison is made with direct experimental measurements of intermediate energy absorption cross sections for several isotopes. Because of the unusually large level spacings for target nuclei which have even proton and neutron numbers or near-magic neutron numbers, the average fission-product cross sections obtained here are lower than those obtained in estimates which ignore this effect. The influence of various assumed statistical distributions of reduced neutron widths on the average cross section is discussed.
