Modifications), the data is accessed through a portable SQLite3 databaseįile. Implemented using the Fortran routine by Brennan and Cowan with slight The anomalous cross-section data from Cromer and Liberman (which is Values for absorption cross-sections and anomalous X-ray scattering factors On the work of Cromer and Liberman, using the Anomalous cross-sections are available as based \(f_0(q)\),is derived from Waasmaier and Kirfel Oliver, while elastic X-ray scattering data, The core-hole widths for excited electronic levelsĬomes from Keski-Rahkonen and Krause and Krause and Much of the X-ray spectroscopic data comes from the compilation of Elam etĪl. The second category allows these elemental properties to be applied toĬommon compounds by name or by chemical formula. Transition probabilites for core electron levels, absorptionĬross-sections, elastic scattering terms, and anomalous scattering factors. Mass, and consists of tabulated values of characteristic energies and The first category includes basic atomic properties like atomic number and Properties of elements, and properties of materials and compounds by Properties, which can be broken into two general categories: X-ray Larch provides several functions to access these X-ray Having access to tabulated values for X-ray properties of various elementsĪnd compounds. An important aspect of X-ray spectroscopies and scattering analysis is
