中子扩散中的简单超对称方法
Simple supersymmetric methods in neutron diffusion
摘要:
我们提出了超对称Witten和双达布(严格等谱)的建设,适用于从无限长线源的热中子扩散。虽然Witten构造只是一个数学方案,但双达布方法引入了一个单参数扩散解族,这些解与稳态解是严格等谱的。它们对应于Darboux变换的扩散长度,
英文摘要:
We present the supersymmetric Witten and double Darboux (strictly isospectral) constructions as applied to the diffusion of thermal neutrons from an infinitely long line source. While the Witten construction is just a mathematical scheme, the double Darboux method introduces a one-parameter family of diffusion solutions which are strictly isospectral to the stationary solution. They correspond to a Darboux-transformed diffusion length which is flux dependent
