| Abstract: | By making use of the facility for radioactive beams which would be able to supply intense high resolution beams of short lived (radioactive) nuclei, the neutron-proton ratio can be extended to extreme values, where some new phenomena such as neutron halo, proton halo, neutron skin, proton skin,growing evidence of the fragility or disappearance of shell structure far from stability, the importance of pairing correlation near drip line, and the possible existence of new superconducting phases of nucleonic matter such as proton neutron pairing etc. will appear. To investigate and understand the phenomena, and then return to experimentally more accesible regions near stability to test our understanding of nuclei will afford a new opportunity to study the nuclear structure, nucleosynthesis and nuclear astrophysics, and fundamental symmetyies in the nature. |
