Binding energies per nucleon increase sharply as A increases, peaking at iron (Fe) and then decreasing slowly for the more massive nuclei. The binding energy divided by c 2 is sometimes known as the “mass defect”.

The Weizsaecker formula is an empirically refined form of the liquid drop model for the binding energy of nuclei. It has the following terms: Volume term; Surface term; Asymmetry term; Pairing term; Using the Weizsaecker formula, the binding energies and also masses of atomic nuclei can be derived. Therefore, we can also derive the energy ...
- In nuclear physics, liquid drop model of nucleus describes forces in atomic nuclei as if the atomic nucleus were formed by a tiny liquid drop. But...

In this model, the so-called liquid-drop model, all nucleons are uniformly distributed inside a nucleus and are bound together by the nuclear force while the Coulomb interaction causes repulsion among protons. Characteristics of the nuclear force (its short range) and of the Coulomb interaction explain part of the semi-empirical mass formula ...
Lecture 4: Binding Energy, the Semi-Empirical Liquid Drop Nuclear Model, and Mass Parabolas. Description: We formally define the binding energy of a nucleus and check our definition with examples from the KAERI Table of Nuclides.
The Liquid Drop Model. This is a simple model for the binding energy of a nucleus. This model is also important to understand fission and how energy is obtained from fission. 104. In the case of a large nucleus a fair number of nucleons are assembled and we know that they attract each other.
We can use the expression for the binding energy given by the liquid drop model to calculate this. Let us suppose that a nucleus ( Z,A ) splits into two ( Z 1 ,A 1 ) and ( Z 2 ,A 2 )
1. Sept. 2013 · We review the evolution of liquid-drop based nuclear mass models over 80 years. • The original 1935 semi-empirical model of binding energies was accurate to 3 MeV. • It was decisive for understanding radioactive decay and interpreting fission. • The macroscopic–microscopic method [28] led to 0.6 MeV accuracy. •
