Rutherford experiment shows that alpha-particles when they fly towards metal foil sometimes (in minority of cases) can bounce. An explanation proposed was that atoms in fact have positively charged nuclea and majority of space is covered by fields of negative charge caused by electrons. Indeed, these fields must have much smaller charge density so that they (almost) don't affect alpha particles.
However, according to this explanation a neutron when it flies towards a nucleus should not bounce because of electromagnetic force. This is because neutron is an uncharged particle. Gravity is too weak to have any significant effect between neutron and nucleus so they don't merge. Weak forcd probably also is too weak. Therefore we can only consider strong force.
So, when a neutron flies towards a nucleus with high speed, what happens? Does strong force come into effect? Or does it just pass through a nucleus?
