Abstract
Intermediate-energy heavy-ion reactions produce a mid-rapidity region or neck, mostly in the semiperipheral collisions. Brief theory and experiment surveys are presented. General properties of the mid-rapidity zone are reviewed and discussed in the framework of reaction dynamics. Hierarchy effect, neutron enrichment, isospin diffusion are all new neck phenomena which are surveyed. The main neck observables are also examined, mainly in the context of the symmetry term of the nuclear equation of state.

It has been proposed to call the Viola-violation-correlation plot as Wilczyński-2 Plot. Indeed this correlation, very important to rule out a statistical fission scenario for fragments produced at mid-rapidity, nicely emerged during hot discussions of one of us (M.D.T.) with J. Wilczyński at the LNS-INFN, Catania. In fact this correlation represents also a chronometer of the fragment formation mechanism. In this sense it is the nice Fermi energy complement of the famous Wilczyński Plot which gives the time scales in Deep-Inelastic Collisions.
