Select an isotope, inspect or edit its cells, and compare absolute or delta wiring definitions. Use File to import or export your work.
Before relying on validation or an export: read Validation and export limits. The hosted legacy editor is separate from the unintegrated incidence/revision machinery; passing counts do not certify full-definition replay or physical adequacy.
These diagrams and counts describe working constructions, not established nuclear geometry or isotope stability. See also the isotope / R-space viewer.
