so why is it exactly that estimating accurately the radius of the nucleus is not possible? Why is it that you only get a bigger estimate than what the radius actually is? I thought you cant estimate it accurately because because the alpha particle gets taken over by the strong force and absorbed by the nucleus (given that the a particle has enough energy to get that close to the nucleus) before reaching the actual nucleus it self?
I'm making some revision so I would like to know why that is.
