Simple derivation of the first cumulant for the Rouse chain
摘要:
推导了Rouse模型中聚合物线团动态结构因子的一阶累积量的简单解析表达式。所得到的公式是准确的通常假设的连续分布的珠沿链。它反映了聚合物的内部运动及其扩散对光或中子的光的散射的贡献,并且在散射时波矢变化的整个区域内都是有效的。
英文摘要:
A simple analytic expression for the first cumulant of the dynamic structure factor of a polymer coil in the Rouse model is derived. The obtained formula is exact within the usual assumption of the continuum distribution of beads along the chain. It reflects the contributions to the scattering of light or neutrons from both the internal motion of the polymer and its diffusion, and is valid in the whole region of the wave-vector change at the scattering.
