Very neutron-rich isotopes of light elements: Nuclear structure

The present study is the second part of a review devoted to the properties of light neutron-rich nuclei. It focuses on the structure of neutron-rich i sotopes of light elements with 2 less than or equal to Z less than or equal to 5 (the isotopes He-6,He-7,He-8,He-9,He-10, Li-10,Li-11, Be-11,Be-12,Be- 13,Be-14, and B-14,B-15,B-16). The results published up to January 1999 are quoted. The latest results have been obtained by using exotic radioactive targets such as C-14 and Be-10, and also radioactive beams. Information is given which sheds light on the properties of light nuclei close to the neut ron dripline. Unusual properties of such nuclei have been observed (neutron halo, neutron skin, energy-level inversion, and so on). The experimental d ata are compared with calculations carried out within the existing theoreti cal models. (C) 1999 American Institute of Physics. [S1063-7796(99)00306-X] .
