Neutrons produced when a spinning proton collides with another proton come out with a slight rightward-skew preference.
But when the spinning proton collides with a much larger gold nucleus, the neutrons' directional preference becomes larger and switches to the left.
The scientists will execute a new series of experiments colliding polarized protons with other kinds of nuclei to study the electromagnetic interaction effect.
