摘要：
Using Radioactive Ion Beams (RIB) new properties of neutron-rich nuclei near the border of stability have been investigated. Properties of these exotic nuclei near the drip line with Z up to 20 have been studied using the direct measurement of the mass of 31 radioactive nuclei at GANIL. The derivation of two-neutron separation energies have enabled to establish new neutron magic number N=6 and 16 in neutron-rich region for the first time instead of normal 8 and 20 and to support the non-existence of doubly magic nuclei He-10 and O-28. Immense changes in basic properties of nuclear matter have been confirmed by novel two step fragmentation in-beam gamma ray spectroscopy that has established the 2(4O) nucleus as a new doubly magic nucleus.
