Nuclear Radius

From the experimental results a graph was plotted of R against A. A graph like the one to the right was obtained. They saw that R depends not on A, but on A^⅓.

When they plotted the graph of R against A^⅓ they found a straight line that cut the origin and had a gradient of r₀. (r₀ is a constant representing the radius of a single nucleon and has a value of between 1.2 and 1.5 fm)

The radius of a nucleus has been found to be:
