![]() The enrichment price range narrowed a bit Restricted prices weakened, but unrestricted prices firmed slightly. Of the twelve deals, three took place in the spot concentrates market, two took place in the medium and long-term market, three in the conversion market, and four in the enrichment market. In total, twelve deals took place compared to 28 deals in August. Volume in the spot concentrates market fell below 1 million lbs U3O8. This article is the September 1994 uranium market summary. ![]() It is shown that in the case of Coulomb repulsion, a two-body scattering amplitude at leading order in a combined expansion is the sum of a Coulomb-modified background term and a Breit-Wigner amplitude with parameters renormalized by Coulomb interactions. The EFT is generalized to describe a narrow low-lying resonance in a system of charged particles. Such an EFT is applicable to systems in which short-distance dynamics generates a low-lying quasistationary state. At leading order in the combined expansion, a two-body scattering amplitude is the sum of a smooth background term of order Q 0 and a Breit-Wigner term of order Q 2 (δε) -1 which becomes dominant for δε 3. ![]() ![]() An effective Lagrangian is formulated in the form of a combined expansion in powers of a momentum Q 0 | 0 -a resonance peak energy. Narrow resonances in systems with short- range interactions are discussed in an effective field theory (EFT) framework. ![]() International Nuclear Information System (INIS) Narrow resonances and short- range interactions ![]()
