§9 · ionization bounds and closing scope

Follow all nine sections: the classical allocation problem, the Wien entropy calculation, independent configurations, the heuristic move, and three energy-transfer applications.

Newly authored explanatory preview in modern notation; editorial and physics review are pending. The introduction and all nine numbered sections have explanatory treatments below, but this is not a German transcription, an aligned English translation, or a complete critical edition. Source faces remain in preparation. The headings and argument units are editorial, not a verified paragraph-by-paragraph source inventory.

A threshold does not specify a yield

Under a one-quantum ionization assumption, a quantum must meet the required ionization energy. Absorbed energy bounds the count; equality requires that every absorbed quantum causes exactly one counted ionization.
