    The liquid drop model is one of the first models of nuclear structure, proposed by Carl Friedrich von Weizsäcker in It describes the nucleus as a semiclassical fluid made up of neutrons and protons, with an internal repulsive electrostatic force proportional to the number of protons. The quantum mechanical nature of these particles appears via the Pauli exclusion principle, which states. Nuclear fission - Nuclear fission - Fission theory: Nuclear fission is a complex process that involves the rearrangement of hundreds of nucleons in a single nucleus to produce two separate nuclei. A complete theoretical understanding of this reaction would require a detailed knowledge of the forces involved in the motion of each of the nucleons through the process. @article{osti_, title = {Recent progress in the microscopic description of small and large amplitude collective motion}, author = {Lacroix, D., E-mail: [email protected] and Tanimura, Y. and Ayik, S. and Scamps, G. and Simenel, C. and Yilmaz, B.}, abstractNote = {Dynamical mean-field theory has recently attracted much interests to provide a unified framework for the description of.

See details - Nuclear Collective Motion Models And Theory. The distribution of 'strength' (the square of the transition matrix element of a one-body operator) to excited states satisfies certain sum rules that ensure reasonable results for inclusive processes, i.e. those in which we do not care about the final nuclear state.

Collective motion is particularly easy to describe. The pairing phase transition is a singular feature of macroscopic superconductors while in nuclei it is smoothed out because of quantum or thermal fluctuations.

On the other hand band crossing, which is associated with the interplay of pairing and nuclear rotations, is a prominent and systematic feature of nuclear : D. Brink. On the Collective Motion in Even-Even Spherical Nuclei Toshio Marumori. Progress of Theoretical Physics Vol. 29 No. 4 () pp.

The adiabatic rotational model is founded upon the rotation group SO(3) and the microscopic extension of the Bohr-Mottelson model starts from the general linear group GL(3,R) [1–11].

Current developments in nuclear structure are discussed from a theoretical perspective. First, the progress in theoretical modeling of nuclei is reviewed.

This is followed by the discussion of nuclear time scales, nuclear collective modes, and nuclear deformations. Some perspectives on nuclear structure research far from stability are by: 3. Introduction In nuclei collective motion exhibits itself in various forms. ranging from vibrations around stable configurations to processes of large scale as encountered in fission and heavy ion collisions.

It was only shortly after the discovery of fission that Kramcrs [ 1 ] suggested one of the first models of nuclear collective by: 8. In the collective model, high-energy states of the nucleus and certain magnetic and electric properties are explained by the motion of the nucleons outside the closed shells (full energy levels) combined with the motion of the paired nucleons in the core.

Roughly speaking, the nuclear core may be thought of as a liquid drop on whose surface circulates a stable tidal bulge directed toward the rotating unpaired. Nuclear Collective Motion: Models And Theory. The two most important developments in nuclear physics were the shell model and the collective former gives the formal framework for a description of nuclei in terms of.

A novel transverse-momentum technique is used to analyse charged-particle exclusive data for collective motion in the Ar+KCl reaction at GeV/nucleon. Previous analysis of this reaction, employing the standard sphericity tensor, revealed no significant by: COVID Resources.

The main features of the nuclear optical model are reviewed, with particular attention to current growth points. The determination of the form and strength of the nucleon-nucleus interaction by calculation from the nucleon-nucleon interaction is described and the results compared with those obtained phenomenologically.

This chapter develops a quantal transport theory for non-linear nuclear collective motion, the coordinates of which are functionals of the nucleonic degrees of freedom, the latter being interpreted as ‘heat bath’.

Introduced on the mean field level the collective variables must be quantized. This is accomplished through the Bohm-Pines method, which leads to an extended Hamiltonian for the Author: Helmut Hofmann.

We deal with the application of the nuclear Born-Oppenheimer (NBO) method to the study of nuclear collective motion.

In particular, we look at the description of nuclear rotations and vibrations. The collective operators are specified within the NBO method only to the extent of identifying the type of collective degrees of freedom we intend to describe; the operators are then determined from Author: Nouredine Zettili, Abdelkrim Boukahil.
