Question

Column II gives the probability of nuclear fission relative to $U^{236}$ for nuclides given in column I match them correctly.

Answer 1

• $A$ Probability of nuclear fission relative to $U^{236}$ is 1
  

• $B$ U-239 has relatively small nuclei of size 0.001 ,which cannot be slit easily
  

• $C$ Pu-240 has relatively large nuclei of size 1.5 which can be splits easily. So probability must increase
  

• $D$ Am-244 has low fission rate of range 0.0002.
