‘‘Tomography’’ of the Cluster Structure of Light Nuclei via Relativistic Dissociation
- 1k Downloads
These lecture notes present the capabilities of relativistic nuclear physics for the development of the physics of nuclear clusters. Nuclear track emulsion continues to be an effective technique for pilot studies that allows one, in particular, to study the cluster dissociation of a wide variety of light relativistic nuclei within a common approach. Despite the fact that the capabilities of the relativistic fragmentation for the study of nuclear clustering were recognized quite a long time ago, electronic experiments have not been able to come closer to an integrated analysis of ensembles of relativistic fragments. The continued pause in the investigation of the ‘‘fine’’ structure of relativistic fragmentation has led to resumption of regular exposures of nuclear emulsions in beams of light nuclei produced for the first time at the Nuclotron of the Joint Institute for Nuclear Research (JINR, Dubna). To date, an analysis of the peripheral interactions of relativistic isotopes of beryllium, boron, carbon and nitrogen, including radioactive ones, with nuclei of the emulsion composition, has been performed, which allows the clustering pattern to be presented for a whole family of light nuclei.

The author considers it his pleasant duty to extend appreciation to his colleagues for the BECQUEREL project. Drawing attention to the cited publications appears to be a suitable form for such an acknowledgement. Nevertheless, the support given by Prof. A.I. Malakhov (JINR) deserves special thanks. It was under his leadership that the beam extraction system from the superconducting Nuclotron was put into operation, making possible our exposures.
The author is sincerely grateful to Prof. C. Beck (University of Strasbourg) for his invitation to write this review. My senior friend Prof. S.P. Kharlamov (Lebedev Physical Institute, Moscow) gave a critical analysis of the initial version. I.G. Zarubina (JINR) made the first proof-text version and prepared illustrations. D.O. Krivenkov (JINR) performed makeups of these notes and of the quoted publications. I.S. Baldina and O.K. Kronshtadtov (JINR) edited the English version.
The preparation of the review was supported by Grant 12-02-00067 from the Russian Foundation for Basic Research and by grants from the Plenipotentiaries of Bulgaria and Romania to JINR.
