ATOMICUS · Fission Scission Map ²³⁵U in opposition-shell packing · central hit → rigid inner sphere + outer skin that calves off

Produce this larger daughter

Ranked by real IAEA thermal-fission yield. A central proton hit (b≈0) makes the outer skin (≈100 nucleons) calve/shear off the rigid inner sphere (α core + the tritons that do not budge) — the sphere is this heavy daughter. (A grazing hit b→R shaves a thin surface chip instead → spallation, NP27.)

Show

inner sphere — rigid core (α + tritons), the N=82 lock

outer skin — ≈100 nucleons that calve off → own atom

shear surface — core/skin boundary (tritons strip → ν)

central proton hit (b≈0)

Scope: subunit counts are exact (α + n_d deuterons + n_t tritons). The opposition-shell positions are the model's assignment (Harvey 2026-07-03), not proven unique. The split is radial (tritons inner, deuterons outer) — what is rigid is the triton core (heavy daughter locks near n_t = 31–32, the N = 82 shell), shown live below.
