Question

The radius of a nucleus determined by electron scattering is found to be slightly different from that determined by alpha-particle scattering. This is primarily because:

Professor PC Thomas Classes · Answer

Electron scattering senses the charge distribution of the nucleus (since it interacts purely via the electromagnetic force), whereas alpha particles sense the nuclear matter due to the strong nuclear force at close range.
