This directory is the working end of the foundational document's central claim: that the entire viability of nuclear computing collapses onto one falsifiable component, the triggered release gate with gain, judged by the leak condition η > ½ and the amplification condition Γ > 1.
| file | what it is |
|---|---|
isomer_screen.py |
screens every isomer in NUBASE2020 (1870 states) and evaluates a curated candidate set; regenerates the catalog, the candidate table, and figure 8 |
isomer_catalog.csv |
every isomer on Earth: excitation energy, half life, λ_m, spin parity, decay modes |
candidates.csv, candidates.md |
the curated candidates with measured multiplicities, trigger mechanisms, energy leverage, and citations |
experiment_menu.md |
required trigger cross sections and fluxes per candidate per facility; where the keystone lives and dies |
edm_plan.py, edm_channels.md |
the computed energy division multiplexing channel plan: eight clean CZT interconnect channels from catalog sources, with leakage matrices and longevity |
data/ |
cached NUBASE2020 and ENSDF decay radiation files (IAEA), so every number is reproducible offline |
Headline numbers, all computed from the data in this directory:
- 1870 isomeric states known; 585 hold a bit for at least one second; 50 are nonvolatile for at least a day; 38 of those store at least 100 keV.
- ⁹³ᵐMo releases β = 2.87 photons per triggered decay (ENSDF intensities), not the vague "few" of the literature.
- ¹⁷⁸ᵐ²Hf releases β = 12.39 photons per release once the 1147 keV chain it feeds is counted, confirming the folklore value of about a dozen from primary data.
- The only rows of
candidates.mdwhere trigger cross section, flux, and multiplicity are all measured quantities satisfying both keystone inequalities are the neutron sector rows (²⁴²ᵐAm, ²³⁵U). Seeexperiment_menu.mdfor what that means.
Run it:
python3 isomer_screen.py
Requires matplotlib for the figure; the CSV outputs need only the standard library. First run downloads and caches the IAEA files.
