如果这个截面大,说明物质能够吸收很多能量;如果小,物质则几乎不吸收光。 最后一个概念:消光截面Extinction Cross-Section σext=σabs+σscat光和纳米颗粒的相互作用,简单来说就是【吸收】加【散射】。那你可能会问,为什么不提【反射】和【折射】呢?其实,光与物质的相互作用本质上确实是通过吸收或散射来体现的。反...

the value of σ does not in general correspond to the geometric cross section of the target. Here we will consider four different types of cross sections, which are commonly used in con- nection with radar. They are the scattering cross section σ ...

Bragg intensities were corrected and brought into agreement with the values used for structure determination in the previous section. The intensities were then placed on an absolute scale. Finally, continuous scattering intensities were accumulated on a fine grid to produce the final diffuse map. The...
The scattering cross section is (3)dσ/dΩ=re2Kpol where Ω is the solid angle, re = e2/mc2 = 2.82 × 10−13 cm is the classical electron radius, and Kpol is the polarization factor. For unpolarized radiation Kpol = (1 + cos2ϕ)/2, where ϕ is the scattering angle. The ...
the total scattering cross-section (Csca) is utilized to show the comprehensive scattering effect on the light source, which is defined as the weighted average of the scattering cross-section according to the intensity distribution of the light source. TheCscaalso gradually increases as the Br co...
