American Journal of Physics, 1960
A summary is given of the development of nuclear models, both for the description of structure and of scattering and reaction processes. The treatment is qualitative, and follows mainly the historical development. Models discussed are the liquid drop model, the potential well model for nuclear reaction processes, the compound nucleus model for nuclear ...

Quasielastic charged-current neutrino-nucleus scattering with relativistic nuclear models [PDF]
Physical Review C, 2023 Charged-current neutrino-nucleus scattering is studied in the quasielastic region with various relativistic nuclear models that include the relativistic Hartree, the nonlinear sigma, the quark-meson coupling, and the chiral quark-meson coupling models ...

Nuclear speckles: a model for nuclear organelles
Nature Reviews Molecular Cell Biology, 2003Speckles are subnuclear structures that are enriched in pre-messenger RNA splicing factors and are located in the interchromatin regions of the nucleoplasm of mammalian cells. At the fluorescence-microscope level they appear as irregular, punctate structures, which vary in size and shape, and when examined by electron microscopy they are seen as ...

Physical Review, 1955
The framework for a unified theory of nuclear structure is described in which the wave functions for different nuclear models are obtained by transformations on the actual nuclear wave function. This formulation provides a basis for explaining the success of weak-coupling models of the nucleus and showing that they are not in conflict with the ...

Nuclear Models and Nuclear Fission
Physical Review, 1961The hindrance to spontaneous fission by the odd nucleon in the fissioning nucleus may be explained as due to the pairing energy of the odd nucleon at the saddle-point deformation. (auth)

Cluster Models in Nuclear Astrophysics
Clustering Aspects of Quantum Many-Body Systems, 2002The general context of low energy reactions in nuclear astrophysics is outlined. Different cluster models, used in this field, are briefly presented. We discuss more specifically the potential model, the R-matrix method and microscopic models. Other techniques are commented on, and recent applications are presented.

Physics Today, 1969
To UNDERSTAND the behavior of the atomic nucleus we resort to models, for the complexity of the problems that we meet demands simplification if progress is to be made.

Model for Nuclear Reactions with Neutrons
Physical Review, 1954A simple model is proposed for the description of the scattering and the compound nucleus formation by nucleons impinging upon complex nuclei. It is shown that, by making appropriate averages over resonances, an average problem can be defined which is referred to as the "gross-structure" problem.

Statistical model of nuclear multifragmentation
Physical Review C, 1989We present a statistical approach to the problem of multifragmentation in heavy-ion collisions. We begin with a generalized Sakur-Tetrode expression for the entropy. Through it we find expressions for the configuration weight functions. Fluctuations in the configurations are shown to be Poisson-like.

Quantitative models of nuclear transport
Current Opinion in Cell Biology, 2005Nuclear pore complexes mediate the rapid trafficking of target macromolecules between the nucleus and the cytoplasm but exclude non-targets. Mathematical modeling helps to define the physical properties of a transport medium that can selectively enhance the permeation of some molecules but block others.
