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

[ZedCar]

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

Approximately. That equation is true for any substance of constant density. That's a pretty good assumption for cold nuclear matter.
