Hi Bob, You seem to be describing a kind of nuclear "band," where there are so many nuclear levels from participating nuclei that they merge into a band analogous to a band in a semiconductor, and the energy levels lose their distinctness and become continuous.
How do the nuclei communicate with one another at a sufficiently fast rate to make such bands possible? The nuclear volume is very small, nuclei are spaced very far apart, and nuclear interactions occur in an extremely short amount of time, such that a virtual photon will not get very far before a strong interaction takes place (e.g., fragmenting of a compound nucleus). Consider that even in a closely packed lattice the nuclei are separated by enormous distances.
