Detailed Description

Seltzer-Berger differential cross section tables for a single element.

The 2D grid data is organized by \( \log E \) on the x axis and fractional exiting energy (0 to 1) on the y axis. The values are in millibarns, but their magnitude isn't important since we always take ratios.

argmax is the y index of the largest cross section at a given incident energy point.

Todo:

We could use way smaller integers for argmax, even i/j here, because these tables are so small.
