Abstract:
The most new scientific opportunities of nuclear physics are: the exploration of the quark degrees of freedom and of the underlying theory of the strong interaction, QCD, in the nuclearmedium; the study of the nuclear equation of state and of quark-gluon plasma (QGP); the study ofnuclear structure at the limits of temperature, angular momentum, and neutron-to-proton ratios; theuse of the nuclear medium for precision studies of fundamental aspects of the strong and...

Abstract:
We introduce the quark delocalization and color screening into the usual quark modeland the property of nuclear force. The resulting N-N phase shifts and the adiabatic potential aredescribed qualitatively well: there are exclusion core and also intermediate range attraction, but thereis no Van der Waals force. The delocalization parameter obtained from variational method is alsoreasonable. we consider especially the effect of mass center motion, the effect of forms of colorscreening...

Abstract:
Both atomic clusters (microclusters) and nuclei are systems of the finite number ofparticles but with different interaction forces among the component particles, and have somesimilarities in their properties, such as saturation, shell structures, magic numbers, isotopic effect,deformation and compound clusters (nuclear) process, etc. The similarities rivet attention in manyscientific communities from nuclear, atomic and molecular, and condensed matter physics as well aschemistry.

Abstract:
The systemaic characters of (n,t) reaction cross sections have been studied for mediumand heavy mass nuclei at 14 MeV. A set of the empirical formulas have been given on the bases of theodd-even effects. The (n,t) reaction cross sections of some nuclei have been calculated, and a goodagreement with the experimental data have been obtained. The Q-value effect and possible reactionmechanism are also discussed.

Abstract:
The working principle of scintillating fibers is briefly introduced in this paper. Thedecay time constant and spectral properties of the scintillating fibers of Tb_2O_3 and Ce_2O_3 glass aregiven. Comparing the properties of materials above and CeF_3 with those of other inorganic scintillatingmaterials, we find that CeF_3 and scintillating fibers of the Ce_2O_3 have an immense potential applicationmarket.
