The behavior of the two-neutron separation energies S_2n derived from mass measurements gives a very clear evidence for the existence of the new shell closure N=16 for Y=9 for Z=9 and 10 appearing between 2s_1/2 and 1d_3/2 orbitals. This fact, strongly supported by the instability of C, N and O isotopes with N > 16, confirms the magic character of N=16 for the region from carbon up to neon while the shell closure at N=20 tends to disappear for Z ó 13. Decay studies of these hardly accessible short-lived neutron-rich nuclei from oxygen to silicon using the in-beam ç-ray spectroscopy are also reported.
