electron-photon interaction amplitudes, which are most relevant for all atomic cascades, the (hyperfine) interaction with the nuclear moments [37,38], the mass- and field-shift amplitudes [39,40], or the Coulomb excitation by charged particles [41] are known to determine the behavior of atoms...
and then the tug would relinquish control of its systems to the target ship's pilot, or a harbor pilot brought on board for the purpose, saving some of the mass of reactor shielding for the cockpit and some of the ulcers for shipmasters, but the UN insisted on doing things the old fas...
