Is a neutron halo nothing but a large neutron skin?

We discuss the difference between neutron halos and neutron skins matching to our usual thinking of a skin as being connected to a body whereas a halo is, in some sense, disconnected from the body. We emphasize that the existence of one or more neutrons behaving incoherently with respect to the rest of the nucleons in a nucleus can match the picture of a neutron halo.

On Possibility of Decoherence in Correlated two Neutral Kaon Systems

We point out that decoherence parameters in the correlated two neutral kaon system breaks the transformation invariance of basis and their magnitude are stringently limited by the experimentally measured magnitudes of CP violation and of the strangeness non conserving $ΔS = \pm 2$ transitions.
