Error bars are shown for all data and represent statistics plus point-to-point systematics (but not not systematics that would shift all the data for a single nucleus). R = R 0 A 1 3 Where R 0 = 1.210 -15 m. From the formula, we can conclude that the volume of the nucleus, which is proportional to R 3, is proportional to A (mass number). A big part of what they do at Jefferson laboratory is to search for the change between nucleon--meson degrees of freedom (as reasonably well described by quantum hadrondynamics) and quark--gluon degrees of freedom (as described by quantum chromodynamics); but even the on-set of QCD dominated behavior does not correspond to quark--gluon plasma which occurs at much higher energies.
