Calculates the maximum energy that can be used to satisfy safe Coulomb excitation based on a user provided minimum separation. The “Cline condition” if selected uses the canonical 5 fm separation, regardless of user input. The scattering angle (in the center of mass frame) can also be specified, although this should be used with caution as nuclear effects can “focus” particles to forward angles, bringing unsafe events into the safe regime.
