| Abstract: | Knowledge of nuclear forces is used to obtain information on the size of the quark core of nucleons. A RMS radius of 0.3–0.5 fm appears to be favored by a quark model of the nucleon-nucleon spin-orbit forces, with both one-gluon and ϱ-, ω-meson exchange qq interactions, depending on the relative strength of these qq interactions. The limitations of this estimate are briefly discussed. |
