Recent Developments in Nuclear Cluster Physics
By H. Horiuchi, K. Ikeda and K. Kato
The physics of nuclear clustering is now showing remarkable developments in many directions. The purpose of this review article is to discuss the recent active developments in nuclear cluster physics. In this review paper, the discussions are mostly focused on structural problems because the characteristic feature of the recent trends is just the remarkable developments in the various problems of structure physics.
Among many studies, representative subjects are
(i) novel-types of cluster structure in neutron-rich nuclei,
(ii) cluster gas states as states with drastically novel-type of nuclear structure,
(iii) microscopic studies of molecular states and superdeformation,
(iv) coexistence mechanism of cluster and mean-field-type states observed in a wide mass-number region,
(v) complex-energy states (resonances) of cluster structure in unbound energy region, and
(vi) ab initio theoretical approach to cluster structure.
Various new phenomena and systems of clustering which are discussed in this article imply the basic importance of clustering dynamics in nuclear many-body systems, which is nothing but the manifestation of the richness of nuclear many-body systems.
