13.11 Nuclear radius of the gold isotope, =
Nuclear radius of silver isotope, =
Mass number of gold, = 197
Mass number of silver, = 107
The ratio of the radii of the two nuclei is related with their mass numbers as :
= = =1.2256
Hence, the ratio of the nuclear radii of the gold and silver isotope is 1.23

The reaction is X²? → Y¹²? + Z¹²?
Binding energies per nucleon are: X=7.6 MeV, Y=8.5 MeV, Z=8.5 MeV.
Gain in binding energy (Q) = (Binding energy of products) - (Binding energy of reactants)
Q = (120 × 8.5 + 120 × 8.5) - (240 × 7.6) MeV
Q = (2 × 120 × 8.5) - (240 × 7.6) MeV = 2040 - 1824 = 216 MeV.
