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.
