Important Questions from Nucleus
- The binding energy B of a nucleus is approximated by the formula B = a 1 A − a 2 A 2/3 − a 3 Z 2 A −1/3 − a 4 (A − 2Z) 2 A −1 where Z is the atomic number and A is the mass number of the nucleus. If \(\rm\frac{a_4}{a_3}\) ≃ 30, the atomic number Z for naturally stable isobars (constant value of A) is

- Considering that the radius of an atomic nucleus, $R$, can be approximated by the formula $R = R_0 A^{1/3}$, where $R_0 \approx 1.2 \times 10^{-15}$ m is the Fermi radius constant and $A$ is the mass number, and the average mass of a single nucleon is approximately $1.67 \times 10^{-27}$ kg. Calculate the approximate order of magnitude of nuclear matter density in $\text{kg/m}^3$.
