Expert Solution
Concept and Principle:
  • The Weizsäcker formula is given by,

B=avA−asA23−acZ(Z−1)A13−asy((N−Z)2A)±ap1A12

Here av is the volume term constant and has a value of 15.5 MeV, as is the surface term constant and has a value of 16.8 MeV, ac is the coulomb term constant and has a value of 0.72 MeV, asy is the symmetric term constant and has a value of 23 MeV, ap is the pairing term constant and has a value of 34 MeV, A is the mass number, Z atomic number, and N is the number of neutrons.

 

  • When the A is odd ap will become zero, when A, Z, and N are even the ap will be positive, and when A is even, Z, and N are odd ap will be negative.
