The first step toward a liquid drop model of the nucleus would then be to postulate a volume term and a surface term in the form ... In the liquid drop model, this is included by using the even-odd nucleus as a reference and adding a correction term which is positive for even-even nuclei and negative for odd-odd nuclei.

More Liquid-Drop Model and the Semiempirical Mass Formula The fact that the density and the binding energy per nucleon are approximately the same for all (stable) nuclei was first noticed in the early 1930s, after a sufficient number of atomic masses had been measured.

The liquid-drop model in nuclear physics was originally proposed by George Gamow and developed by Hans Bethe and Carl von Weizsäcker in the 1930s. It treats the nucleus as an incompressible fluid of protons and neutrons bound together by the strong nuclear force.

3 The Liquid Drop Model; 3.1 Some Nuclear Nomenclature; Nucleon: A proton or neutron. Atomic Number, Z: The number of protons in a nucleus. Atomic Mass number, A: The number of nucleons in a nucleus. Nuclide: A nucleus with a specied value of A and Z. This is usually written as;

Contents of Liquid drop model and mass formula ... Now we have some basic information about the liquid drop model, let us try to reinterpret the mass formula in terms of this model; especially as those of a spherical drop of liquid.

The macroscopic deformed potential energy for super-heavy elements Z = 120 is determined within a generalized liquid drop model (GLDM). The shell correction is calculated with the Strutinsky method and the microscopic single particle energies are derived from the shell model in an axially deformed Woods–Saxon...

A generalized finite-range liquid-drop model based on the Yukawa-plus-exponential potential was applied to describe fission dynamics of hot rotating nuclei. The potential energy, level-density parameter and Helmholtz free energy are calculated in a consistent way by using the generalized finite-range liquid-drop model.
