Nuclear Radius Equation R = R0 A^(1/3)

#1
If using the nuclear radius equation:

R = R0 A^(1/3)

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

To be fair, even using 1fm would probably be good enough as it is an approximation anyway

I know this is an old thread but are we expected to memorise the value of R0?
