The neutron and proton driplines are now achieved in broad ranges both on proton-rich and on neutron-rich sides of the nuclide map. It is then natural to expand our knowledge to particle unstable systems represented by states in continuum. Many of such states beyond for the driplines are demonstrating unusual forms of nuclear dynamics which we characterize as few-body phenomena. Among them are two-proton radioactivity, democratic decays, soft excitation modes in the three-body continuum. "True" two-neutron and "true" four-neutron emission in extreme situation of low decay energy may lead to existence of 2n or 4n radioactive decays.
Several recent theoretical results concerning the few-body phenomena in the dripline nuclear systems are discussed. The relevant experimental studies at Flerov Lab are briefly reviewed. The recent experiments belonging to this class of physical phenomena performed at NSCL (45Fe, 6Be, 10He, 26O) are discussed from theoretical point of view.
