INTRODUCTION Fig. I i'only one of the various possible systematic arrangements of the elements that occur in nature, or have recently been produced. The elements are arranged i n order o f increasing atornir number. indicated by the fignre immediately below the sytnbol of each element. Nuclear physiriqts th ink of tlie atornic number Z as the runnber of positively charpcl particles. called prot...
The field of nuclear archaeology aims to develop the methods and tools to verify past production of fissile materials for military purposes, which may become necessary to support the verification of future arms control agreements that envision deeper cuts in the nuclear arsenals. Techniques have been successfully demonstrated for reconstructing historic plutonium production, especially in graph...
We consider the Maxwell-Stefan model of diffusion in a multicomponent gaseous mixture. After focusing on the main differences with the Fickian diffusion model, we study the equations governing a three-component gas mixture. Mostly in the case of a tridiagonal diffusion matrix, we provide a qualitative and quantitative mathematical analysis of the model. We develop moreover a standard explicit n...
