Question

If $M$ is the mass of nucleus and $A$ its atomic mass, then the packing fraction is:

• A. $\frac{M - A}{M + A}$
• B. $\frac{M - A}{M}$
• C. $\frac{M - A}{A}$
• D. $\frac{M + A}{M - A}$

Hint:

Packing fraction measures the deviation of nuclear mass from integer atomic mass.

Answer 1

The Correct Option is C

Packing fraction is given by:
$$\frac{M - A}{A}$$ where $M$ is the actual mass of the nucleus, and $A$ is its atomic mass.
