Skyrmion model of a nucleus
= Skyrmion model of a nucleus
{c}
{title2=$B=A$}
A charge-$A$ multi-<Skyrmion> provides an intrinsic field configuration for an <atomic nucleus> with <mass> number $A$. Its spatial and <isospin> <collective coordinates> must be quantized, with <Finkelstein-Rubinstein constraints>, before assigning physical nuclear states. A classical intrinsic shape is distinct from rotationally invariant observables in a spin-zero state.
