Lattice:
- Au FCC: a=4.08 Å — 4 atoms per cubic cell — positions (0,0,0) (0.5,0.5,0) (0.5,0,0.5) (0,0.5,0.5) — 4×4×4 = 256 Au atoms — Au metallic yellow full d10 s1 blood gold core metal analog
- At substitutional: replaces Au at [2,2,2] center — At black metallic halogen — 12 Au nearest neighbors — Au-At bond metal analog — lattice constant same metal analog scaled
- Other metal analogs: Ag white electrum, Cu orange copper, Hg silvery liquid, Tl bluish, Pb gray, Bi brittle, Po silvery rare, Obsidian black glass, Fe blood, Pt white gold
-211mN in lattice:
- At-211 α 5.87 MeV — p=1.12e-19 kg m/s — recoil Bi-207 equal opposite — recoil energy E_recoil = p²/(2M) = ~90 keV real — metal analog scaled to -211mN thrust
- Knock-on: Au displacement threshold ~25 eV — Bi recoil 90 keV >> 25 eV → displaces Au neighbors → cascade — 1 At → ~3-5 Au displaced metal analog — -211mN × lattice
- Po-211 7.45 MeV — p=1.26e-19 — E_recoil ~114 keV — -268mN analog — 1.27× more displacement — ~4-7 Au displaced
-211mV in lattice:
- α q=2e — leaves At+? Actually At-211 → Bi-207 + α — At neutral → Bi-207 + α + recoil — charge +2 lost — ionization — Au neighbors capture charge — -211mV drop metal analog
- Po-211 → Pb-207 + α — same — -268mV analog — larger ionization track — α creates electron-hole pairs along path — Au lattice ionizes
- Voltage map: Au atoms near track get +mV, At site gets -211mV, track gets -211mV
Healing:
- Au lattice self-heals — displaced Au interstitial returns — vacancy + interstitial recombine — metal analog healing — Obsidian analog as vacancy
Graph:
- displacement vs decays — Å
- charge mV vs decays — -211mV spikes
- energy eV vs decays — damage energy
