Nuclear Physics — Data Braids

AME2020 nuclear masses (1.2 MB) with full sweetGrass provenance braid. The reference table for GPU-accelerated binding energy calculations.

Experimental nuclear mass data — the ground truth for lattice QCD and nuclear binding energy calculations on sovereign GPU hardware.

Atomic Mass Evaluation 2020. Experimentally measured and predicted masses for 3,500+ nuclides. The international reference table for nuclear binding energy calculations, maintained by the IAEA Nuclear Data Section.

What’s Possible

  • Direct input for hotSpring nuclear binding energy calculations on GPU
  • Validate lattice QCD results against experimental nuclear masses
  • Cross-reference with hotSpring QCD trajectories (see pseudoSpore: hotSpring QCD)

This dataset + hotSpring + consumer GPU = nuclear physics validated against experimental data, running in a basement. The data braid proves the AME2020 table is unmodified; the hotSpring NFT proves the physics was computed correctly.
