Question

Using semi empirical mass formula find the most stable isobar for a nucleus having odd a

Answer 1

Answer:

By utilizing the Semi-empirical Mass Formula demonstrated for fixed odd mass number let say, A, the most stable isobar has a neutron to proton ratio ( N : P) that can be explained by:

Equation:

$\frac{N}{Z} = 1 + a_{c} A^{2/3} / 2a_{A}$

Relevant Equation:

$B ( A , Z ) = a_{V} A - a_{S} A^{2/3} - a_{C} Z^{2} A^{- 1/3} - a_{A} (Z-N)^{2} / A + pairing term.$
