Hi! I am extremely confused on what seems to be quite a simple question. The question contains a graph of root mean square radius <r[itex]^{2}[/itex]> plotted against A[itex]^{1/3}[/itex] where A is the nucleon number. In the lecture notes he specifies that <r[itex]^{2}[/itex]> is not the same as R but does not really say specifically what the difference is. It is given that the gradient of the line in this graph is 0.96. I am meant to find the value of R[itex]_{0}[/itex] in the relationship R=R[itex]_{0}[/itex]A[itex]^{1/3}[/itex] but I'm not certain how to find it because I dont know what the relationship between the rms r and R is.

Any help would be amazing.

I have worked through trying to use the charge radius but without success, he never mentioned the charge radius in the lecture so I'm not sure what to do. http://en.wikipedia.org/wiki/Charge_radius
