Abstract :
In halo nuclei like 11Li and 12Be, polarization effects based on the particle-vibration coupling mechanism leads to a density dependent pairing interaction which provides most of the observed correlation energy which stabilizes the least two bound neutrons. The same mechanism is at the basis of the parity inversion phenomenon observed in 10Li and 11Be.
