If using the nuclear radius equation:
R = R0 A^(1/3)
as shown half-way down this page:
http://en.wikipedia.org/wiki/Atomic_nucleus
r0 = 1.25 fm = 1.25 × 10−15 m
Is this value for r0 always this value, irrespective of the material in question? For example, if it was gold, or some other material?
Thanks

Yes - its the average radius of a nucleon.
There are different figures used depening how r has been measured - the density of a nucleon doesnt drop as a step function.

I know this is an old thread but I'm a bit confused.
My textbook tells me its 1.05fm but my cgp textbook quotes it as 1.4fm. Would I gain the marks if i used either number?

It's an empirically determined constant and is usually quoted to be between 1.2 and 1.5fm

Thanks. I plan to just stick to 1.25 unless told otherwise
