Abstract
We have surveyed the neutron separation energies (S-n) and the interaction cross sections (sigma(1)) for the neutron-rich p-sd and the sd shell region . Very recently, both measurements reached up to the neutron drip line, or close to the drip line, for nuclei of Z less than or equal to 8. A neutron- number dependence of S-n shows clear breaks at. N = 16 near the neutron dri p line (T-Z greater than or equal to 3), which shows the creation of a new magic number. A neutron-number dependence of sigma(1) shows a large increas e of sigma(1) for N = 15, which supports the new magic number. The origin o f the new magic number is also discussed.
