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 dijet double-differential cross section is measured as a function of thedijet invariant mass, using data taken during 2010 and during 2011 with theATLA... I Sadeh - 《Statistics》 被引量: 8发表: 2013年 Four-jet production via double parton scattering in $pA$ collisions at the LHC We...
Differential cross section, polarization observables, and phase-shift and mixing parameters up to L=4 and J<=11/2 are calculated for p-d and n-d elastic scattering below the breakup threshold. The method consists in an expansion of the wave function in terms of the pair correlated hyperspher...
This letter investigates the sensitivity of the ocean surface bistatic scattering cross section measured by the Cyclone Global Navigation Satellite System (CYGNSS) to wind direction using the kurtosis of the delay-Doppler map (DDM) samples within a given area. The azimuthal dependence of the kurtosis...
The elastic scattering cross-section for proton scattering from tritium was measured at a laboratory angle of 165° and over an incident proton energy range from 1.4 to 3.4 MeV. A thin solid target containing 1.62 × 10~(17) T atoms/cm~2 was prepared by absorption of tritium into a film...
By combining a detailed computation of the Lyα scattering cross-section with a standard Λ-cold dark matter cosmology, we investigate the accurate intergalactic absorption profiles of neutral hydrogen. Various Lyα absorption systems in the spectra of distant quasars provide crucial measurements of the...

then the cross section σ can be directly calculated using σ(θ, φ) = 4πr 2 S r (θ, φ) S i , (1) where r is the distance between the target and the observer. In general, the scattering cross section will depend the angles θ and φ. That is, the scatter is not truly ...
