Eighteenth International Workshop on Nuclear Theory
Rila Mountains, Bulgaria
June 7-12, 1999
From 7-th to 18-th June, 1999, the 18-th International Workshop on Nuclear Theory was held at the Scientific House of the Sofia University "St.Kliment Ohridsky" in the Rila Mountains for about 40 participants.
The Workshop is organized every year by the Nuclear Theory Group of the Department of Theoretical Physics in the Institute of Nuclear Research and Nuclear Energy (the Bulgarian Academy of Sciences) and the Faculty of Physics of the University of Sofia. This year it was partly sponsored by the Bulgarian National Science Foundation, the Bulgarian Committee for Peaceful Use of the Atomic Energy, the Bulgarian Nuclear Society and by the Institute of Nuclear Research and Nuclear Energy (Contract No.1693).
Lecturers and participants from Bulgaria, Czech Republic, Germany, Greece, Italy, Japan, Netherlands, Poland and Romania took part in the Workshop. A wide range of topics in the field of nuclear physics has been treated in the lectures, contributions and discussions.Lecturers and participants from Bulgaria, Czech Republic, Germany, Greece, Italy, Japan, Netherlands, Poland and Romania took part in the Workshop.

Prof. K. Tanabe gave a lecture devoted to the angular-momentum projected constrained Hartree-Fock-Bogoliubov calculation of B(E2) for deformed nuclei. The cluster decay and the complex fission modes were subject of the lecture of Prof. D. Poenaru.
The study of the correlation effects in electromagnetically induced two-nucleon knockout reactions from 16O was discussed by Prof. C. Giusti. In the lecture of Dr. M. Gaidarov single-particle overlap functions and their application to one-nucleon removal reactions, such as (p,d), (e,e'p), (e,e'n) and (gamma,p), were presented. Deformed Skyrme Hartree-Fock-Bogoliubov calculations for drip-line nuclei were shown by Prof. M. Stoitsov. N. Tsoneva gave a lecture devoted to the isomeric ratios in odd N=81 isotones.
The character and the exploitation of 1+ states in heavy nuclei were considered in the lecture of Prof. R. Hilton. The pseudo-spin symmetry hidden in the Dirac equation was discussed by Prof. K. Sugawara-Tanabe. Nucleon form factors were considered by Dr. P. Demetriou within a chiral constituent quark model. A systematic study of the effect of short-range correlations on the form factors, densities and momentum distributions of s-p and s-d shell nuclei was reported by H. Moustakidis.
In the lecture of Prof. A. Marcinkowski the sum rule analysis of low-energy direct nucleon reactions was shown and discussed together with a novel onestep cross section formula. Dr. A. Proykova gave a lecture devoted to the finite-size scaling analysis of simulated phase transitions in small systems. SU(3) dynamical symmetry and odd-even staggering in heavy deformed nuclei were considered in the lecture of Dr. N. Minkov. The high-spin structure of 87,88,89,90,91Sr obtained in heavy-ion induced fission was the subject of the contribution of E. Stefanova.
Prof. D. Bonatsos gave a lecture devoted to the structural similarities of nuclei, molecules and atomic clusters. A new study of the rotations of rare earth region nuclei was discussed by Dr. V. Garistov. The effects of the alpha-cluster internal structure on charge form factors of 12C were subject of the lecture of D. Kadrev. Prof. V. Nikolaev gave a lecture devoted to quantum mechanics and field theory in discrete time. The time in the description in cognitive systems was considered in the contribution of Dr. R. Nikolaeva. Spin-orbit interaction in the framework of the method of the reduced density matricies and density functional theory of many-electron systems was reported by A. Kuleff.
In the lectures of Prof. H. Wolter the nuclear structure and reactions in relativistic mean-field theory and preequilibrium reactions were discussed. A. Henneman gave a lecture devoted to quarks with transverse momentum in hard processes. Neutron-proton pairing within algebraic models was the subject of the lecture of Prof. J. Dobe\v{s}.
As in the previous years, during the rest hours the participants visited the attractive high-mountains places in the Malyovitza region of the Rila Mountains and the famous Rila Monastery.
The next 19-th Workshop on Nuclear Theory is planned to be held in June 2000.
