Yeah, a chain reaction that only goes off on a precise atomic alignment could give you that razor‑sharp burst you need. The key is a flawless trigger—no room for error. I'd build a micro‑sensor to watch the alignment and a safety lock that holds the chain at bay until the moment is perfect. It’s efficient, but if the lock fails the blast could be catastrophic. Precision is the only way to keep it from going overkill.
