Nuclear Density




Nuclear density is the Density of the Nucleus of an Atom , about 10^{18}\mathrm{kg}/\mathrm{m}^{3}; Neutron Stars reach this density. Nuclear density is often applied to situations where very high, or nuclear densities occur. Probing within atomic nuclei, one finds quarks which appear to be very dense and very hard. From Deep Inelastic Scattering , it has been estimated that the "size" of an Electron , if it is not a point particle, must be less than 10^{-17} meters. Its density would be roughly 10^{21} \mathrm{kg}/\mathrm{m}^3. The Proton is ''not'' fundamental (as it is composed of Quark-gluon Matter ), but its size is approximately 10^{-15} meters and its density is 10^{18} \mathrm{kg}/\mathrm{m}^3. When it comes to Quark Matter , or Gluon Matter , or Neutrino Matter there are possibilities for still higher densities. The highest densities accessible to us in experiments will likely be limited to Leptons and Quarks in the immediate future. Some related terms you will run into are Nuclear Equation Of State , Nuclear Matter , Quark-gluon Plasma , and Nuclear Compressibility .
