X射线吸收和衰减数据
http://physics.nist.gov/PhysRefData/FFast/html/form.htmlElement:*
- OR - Compound* formula or element symbol:
(e.g., H2O for water)
Type of Data: (Database Holdings)
Energy Range:Energy Range 0.001 - 2.00 keVEnergy Range 2.00 - 433 keVSub Range - keVρ (g cm-3) (optional, only used for the linear attenuation coefficient μ):
No frames.
Data in HTML tables.
*High uncertainties at low x-ray energy (<1 keV):
See estimated uncertainties for elements in Table II of the JPCRD 2000 article.
At low energy, uncertainties may be greater for compounds than elements.
