Determination of the temperature dependence of the elastic stiffness coeffici...

We propose to determine the temperature-induced change of c11 and c44 of UO2 across the Neel transition at 30 K using sound velocities determined with high resolution IXS...本研究拟通过高分辨非弹性X射线散射（Inelastic X-ray Scattering, IXS）测得的声速，测定二氧化铀（UO₂）的c₁₁与c₄₄在30开尔文奈耳转变（Neel transition）过程中受温度诱导的变化……
