Description
During the past several tens of years, our knowledges about the features of exotic nuclei have been much enhanced. In 1980s, neutron halo structure of neutron drip-line nucleus, which is one of the most notable abnormal features of exotic nuclei, have been found. In 1990s, the vanishing of the N = 20 magic number for neutrons have been more extensively studied and discussed in so-called "island of inversion" region.
In this presentation, precise reaction cross section data which have been recently measured at RIKEN, RI-beam Factory using BigRIPS fragments separator for 20-32Ne and 24-38Mg will be reported. The deformation features of Ne and Mg isotopes in the island of inversion and the possible "deformed halo" structure in 29, 31Ne and 37Mg will be presented from our data and the analysis with the microscopic double-folding model (DFM) and anti-symmetrized molecular dynamics (AMD) calculation.
