(we refer to this paper as I in the follow in g).~>)Gross feature of clustering phenomena is the nucleon-density localizations. The M. 0. model treats these density localizations on the basis of Hartree-Fock approximation for nuclear intrinsic states.17) The Hartree-Fock field is determined self-consistently and each nucleon is assumed to move independently of each other in the resulting field. Because the field extends all over the nucleus, the single-particle orbital thus obtained is expected also to move all over the nucleus. Contrary to the usual picture, however, the by guest on March 22, 2015 http://ptps.oxfordjournals.org/ Downloaded from = AA !-
