Nucleons

Some articles on nucleons, nucleon:

Basic Properties of The Nuclear Force
... At small separations between nucleons (less than ~ 0.7 fm between their centers, depending upon spin alignment) the force becomes repulsive, which ... This repulsion is to be understood in terms of the Pauli exclusion force for identical nucleons (such as two neutrons or two protons), and also a Pauli exclusion between quarks ... the nuclear force also has a "tensor" component which depends on whether or not the spins of the nucleons are aligned or anti-aligned ...
Interacting Boson Model
... is a model in nuclear physics in which nucleons (protons or neutrons) pair up, essentially acting as a single particle with boson properties, with integral spin of 0, 2 or 4 ... The IBM-I treats both types of nucleons the same and considers only pairs of nucleons coupled to total angular momentum 0 and 2, called respectively, s and d bosons ...
Atomic Nucleus - Nuclear Models - Shell Models and Other Quantum Models
... A number of models for the nucleus have also been proposed in which nucleons occupy orbitals, much like the atomic orbitals in atomic physics theory ... These wave models imagine nucleons to be either sizeless point particles in potential wells, or else probability waves as in the "optical model", frictionlessly orbiting at high speed in potential wells ... In these models, the nucleons may occupy orbitals in pairs, due to being fermions, which allows to explain even/odd Z and N effects well-known from experiments ...
Nuclear Structure - The Shell Model - Basic Hypotheses
... It was previously used to describe the existence of nucleon shells in the nucleus according to an approach closer to what is now called mean field theory ... The nucleons interact only via a two-body interaction ... is in effect a practical consequence of the Pauli exclusion principle the mean free path of a nucleon being large with respect to the nucleus size, the probability ...
