[en] The concept that quantum chaos is a kind of statistical relaxation process within a finite time for quantum systems with discrete spectrum is first introduced. Then nuclear statistical theories on both fluctuations and mean properties are discussed as consequences of chaotic motions in nuclei

[en] The recent upgrading of the Heavy Ion Research Facility Lanzhou (HIRFL) is briefly introduced with an emphasis on the development of Radioactive Ion Beam Line Lanzhou (RIBLL) at the accelerator. The progresses in the physics research in IMP are reviewed including the studies of hot nuclei and synthesis and studies of nuclei far from stability

[en] The authors propose to introduce a new stochastic process in antisymmetrized molecular dynamics in order to describe the phenomena caused by the wave packet spreading such as the nucleon emission process from a hot nucleus. The authors give the fluctuations originating from the width of the nucleon wave packet to the nucleon stochastically. The authors show by calculating the liquid gas phase equilibrium that the authors can recover the quantum mechanical statistical property of the nucleus for the particle emission process. This improvement also has large effects in the fragmentation in heavy ion collisions such as ⁴⁰Ca + ⁴⁰Ca system at 35 MeV/u. In usual AMD the reaction is almost always binary, while the yield of intermediate mass fragments increases after the incorporation of the effect of the wave packet width

[en] The author deals with following aspects: Nuclear structure of superheavy elements- experiments and predictions 1995;Approaching the Pb-Limit at SHIP/GSI;Production cross section of SHE;The discovery of elements 110 to 111;Towards a fast ,direct reaction mechanism- heavy clusters,completeness and precompound n-emission

[en] The first experiments made at GANIL with the neutron detector Demon are described and their preliminary results presented

[en] The authors present the Boltzmann-Langevin approach which provides a description of the strongly out of equilibrium dynamics encountered in the course of violent heavy-ion collisions. After having introduced the Boltzmann-Langevin model, the authors present some applications to situations where fluctuations are expected to play an important role: the production of kaons at very low beam energy, well below the nucleon- nucleon threshold and the study of nuclear multifragmentation

[en] Complete fusion of massive nuclei is considered in the framework of the dinuclear system concept and the macroscopic dynamical model. The competition between complete fusion and quasi fission in the massive dinuclear systems is discussed. The reality of the dinuclear system concept is demonstrated for symmetric and asymmetric reactions. The synthesis of superheavy nuclei is discussed in the framework of this concept

[en] The Projected Shell Model (PSM) of Hara and Sun is reviewed. This is a shell model developed for the medium to heavy systems. Although the model can be applied to a variety of collective modes, its current numerical code is primarily designed to study nuclear structure of well deformed systems, in high and low spin states. The authors will give a general discussion of the model and its relationship with the algebraic approaches such as the Fermion Dynamical Symmetry Model, and also show various applications to the physics of high spin spectroscopy, level statistics (or 'quantum chaos'), and ΔI = 4 bifurcation

[en] The high sensitivity of Accelerator Mass Spectrometry can be usefully exploited for on-line measurements of low cross sections of astrophysical interest. The utilization of this technique for the case of the reaction ⁷Be(p, γ)⁸B is discussed

[en] Some recent results on the production of hard photons in intermediate energy heavy-ion reactions are reported. The topics covered are the use of hard photons as a means to study the energy dissipation mechanism in peripheral heavy ion reactions and the observation of second chance or thermal hard photons
