Clustering effect is one of the most important phenomen in many areas of physics. For instance, it is well known that there is the cluster of carbon atoms (such as Fullerene) in atom and molecule physics. In nuclear physics, there are many phenomena directly related to clusters, such as alpha decay and cluster decay. Extensive theoretical works have been devoted to studying the important clustering effects, such as clustering in light N=Z nuclei, clustering in neutron-rich nuclei close to drip line and low density nuclear matter, exotic cluster radioactivity in medium mass and heavy nuclei, cluster production in heavy-ion collisions and clustering in astrophysics etc. The clustering effect is also essential to achieve a microscopic description of the masses of nuclei and the correlations between nucleons, such as np correlation. Experimentally, considerable evidence of clustering in nuclei has already been found owing to the fast development of techniques, e.g. the alpha-cluster structure in both ground and excited states in light nuclei. In heavier mass region experiment has also shown that there are more than 500 nuclei exhibiting various cluster emission phenomena, including alpha and other heavier clusters. The study of alpha cluster emission is one of the most important methods to identify newly synthesized superheavy nuclei. Moreover, clustering phenomena also manifest themselves in nuclear breakup reactions and transfer reactions. While significant experimental progress has been made in recent years, much more work needs to be done to pursue a quantitative description of clustering phenomena in nuclei. This program will aim to exchange of ideas, to discuss and to cooperate in this field from both the experimental and theoretical sides. It will offer a better opportunity as well as enough time for the participants to discuss new results in this field.


The objective of this program is to achieve more comprehensive understanding of clustering phenomenon in nuclei. The subjects of this program will include as many subtopics of clustering as possible because there is a growing number of research groups worldwide interested in this fast developing field.

(1) Alpha decay, Cluster Radioactivity, and Spontaneous Fission
(2) Alpha Clustering and Condensates.
(3) Cluster Structure in Light Nuclei.
(4) Clustering in Breakup Reaction, Transfer Reaction and Heavy-ion Reaction.
(5) Nuclear Masses and np correlations.

Plan on this program:
This is a four-week program. The first week will be like a conference and talks will be given in the morning and afternoon (from Monday morning to Friday morning). From the second week to the fourth week, there will be one or two talks each day and the remaining time is for discussions and researches.
