Flat out wrong. That’s what a team of Duke researchers has discovered, much to its surprise, about a long-accepted explanation of how nuclei collide to produce charged particles for electricity – a process receiving intense interest lately from scientists, entrepreneurs and policy makers in the wake of Japan’s nuclear crisis.
