Nucleus: Composition, Size & Nuclear Force

The radius of germanium (Ge) nuclide is measured to be twice the radius of ${}_{4}^{9}$ Be. The number of nucleons in Ge are

Show answer and solution

Answer: (a)

$R \propto A^{1/3} \Rightarrow A \propto R^3$ .
$\frac{A_{Ge}}{9} = 2^3 = 8$
$A_{Ge} = 72$
So the answer is (a) 72.
