Particle/Thin Film Model
The geometric particle and thin film models are:
Thin Film or Thick Polished Section (unsupported film or no substrate)
Rectangular Prism (flat top and flat sides or cube) - sides orthogonal to spectrometer axis
Tetragonal Prism (flat top and curved sides) - sides 45 degrees to spectrometer axis
Trigonal Prism (curved top and flat sides or fiber) - long axis perpendicular to spectrometer
Square Pyramid (curved top and curved sides or sphere)
Backscatter-Modified Rectangular Prism (modified rectangular prism)
Note that the last model is the same as the previous "Rectangular Prism" model with a modified electron side-scattering correction.
Note that particle and thin film calculations are limited to the following standard Phi-Rho-Z correction methods:
Select Individual Corrections (use with caution)
Armstrong/Love Scott (default)
Packwood Phi(pz) (EPQ-91)
Bastin (original) Phi(pz)
Bastin PROZA Phi(pz) (EPQ-91)
Note also that if using "Select Individual Corrections", only the following absorption corrections are allowed:
Phi(pz) Absorption of Packwood-Brown 1982/XRS Alpha
Phi(pz) Absorption of Bastin 1984/XRS Alpha
Phi(pz) Absorption of Armstrong/Packwood-Brown 1981 MAS
Phi(pz) Absorption of Bastin 1986/Scanning
Phi(pz) Absorption of Riveros 1987/XRS
Phi(pz) Absorption of Packwood (New)
Phi(pz) Absorption of Bastin Proza (EPQ-91)
