Description

  • Test our interpolation math
  • Identify the tabulated points to interpolate between
  • Implement xsection() functions to calculate interpolated cross-sections
  • Include the interpolation scheme identifier from ENDF in the generated code.
  • Check that we apply the correct interpolation scheme within a given energy window.

Research direction

Start with the existing interpolation math tests and trace the xsection() functions and generated-code path. Identify the tabulated points and ENDF interpolation identifier, then verify that each energy window uses the correct scheme and that the generated cross-sections match the tests.
