Expert Solution
Concept and Principle:
  • The Weizsaecker formula is used to calculate the binding energy of the atomic nuclei. It is a refined form of the liquid-drop model of atomic nuclei.

 

  • It is formulated from empirical measurements and theoretical data and includes five terms volume, surface, coulomb, asymmetry, and pairing.

 

  • The Weizsäcker formula is given by,

B=avA−asA23−acZ(Z−1)A−as(N−Z2A)±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.
