"To demonstrate this simultaneity is by no means trivial, because it may for example happen that the product nucleus always forms in an activated state at first"
About this Quote
Bothe is doing something many great experimentalists do in print: policing the boundary between a tidy theoretical claim and the messy business of proving it. “Simultaneity” sounds like a clean, almost philosophical notion, but in his hands it’s a laboratory problem with teeth. The sentence is a warning shot against casual inference. If you want to claim two events are truly simultaneous, you have to show your detectors aren’t merely producing a convincing illusion of timing.
The key move is the phrase “by no means trivial.” It’s understated, almost polite, but it carries the authority of someone who has watched elegant arguments collapse under instrumentation. In early nuclear and cosmic-ray physics (Bothe’s domain), coincidence methods were revolutionary precisely because they promised a way to connect cause and effect across tiny timescales. Yet Bothe reminds you that nature (and your apparatus) can cheat: the “product nucleus” might be born “in an activated state,” meaning it can shed energy, decay, or emit radiation after a delay. That delay can masquerade as simultaneity or destroy it, depending on how your measurement is set up.
Subtext: the experiment is not just reading off reality; it’s negotiating with it. Bothe’s intent is methodological discipline: don’t confuse the timing signature of a secondary process with the primary interaction you’re trying to establish. The line also reads as a quiet defense of rigor in a period when nuclear processes were being mapped faster than their hidden intermediate states were understood. In one sentence, he elevates a technical caveat into a philosophy of proof.
