Estimating the size of nucleus


How do you figure out the size of a nucleus?  Especially, a Helium-4 nucleus.

Do you have any good charts online I could use?

I would appreciate it if you would write back.



An estimate of the size of nucleus (nuclear radius) can be made from the empirical formula  where R0 is an empirical constant whose value is 1.25 x 10-15m, A is the mass number.

The following document may be helpful to you for further information
