New Approach to Nonperturbative QCD
Yang Ze-sen, Zhou Zhi-ning, Zhong Yu-shu
1995, 12(2): 1-6. doi: 10.11804/NuclPhysRev.12.02.001
Abstract:
We explain the ideas of the light - front QCD and describe an outline of Wilson S approach to nonperturbative QCD.
Synthesis and Study of Neutron-rich Nuclides
Luo Yi-xiao
1995, 12(2): 7-12. doi: 10.11804/NuclPhysRev.12.02.007
Abstract:
During the past few years our understanding of the decay properties and nuclear structure has been extended in a systematic fashion for the neutron-rich nuclei. This review will first sketch the production and identification of the neutron-rich nuclei throughout the whole mass region, and will then discuss the impressive progress in the studies of the exotic decay properties and nuclear structure of neutron-rich nuclei.Their astrophysical
From Baryon Interactions to Dibaryons
Wang Fan, Ping Jialun, Wu Guanghan, Teng Lijiang
1995, 12(2): 13-26. doi: 10.11804/NuclPhysRev.12.02.013
Abstract:
A new quark potential model, called quark delocalization and color screening model, has been proposed.This model yields both N-N repulsive core and intermediate range attraction without involving the meson exchange and fits the N-N 1S0,3S1,1p1and 3Pls phase shifts qualitatively. It verified dynamically that there might be two kinds of dibaryons.One is the deuteron like low spin, loosely binding two baryon states.The other is the high spin, strong binding six quark states, d. is a typical example and is...
Recent Experiment Status of High Energy Physics
Zhu Yu-can
1995, 12(2): 27-31. doi: 10.11804/NuclPhysRev.12.02.027
Abstract:
The recent experiment status of high energy physics in the world are presented briefly.The evidence for the TOP quark,precision test of EW interaction, heavy flavor physics and lepton physics are summarized in the first part. The second part introduces the new results on τ mass measurement,ψ decay,Ds decay and J/ψ decay performance from BES.
The Multi-fragmentation of Hot Nucleus
Dai Guang-xi, Wu He-yu, Li Zu-yu, Jin Gen-ming, Luo Qing-zheng
1995, 12(2): 32-40. doi: 10.11804/NuclPhysRev.12.02.032
Abstract:
A summary status of experimental and theoretical research in multi-fragmentation of single hot nucleus both in home and abroad is reviewed, especially some experimental results performed at Lanzhou recently are reported in detail.
Nuclear Structure in Exotic Conditions
Chen Yong-shou
1995, 12(2): 41-46. doi: 10.11804/NuclPhysRev.12.02.041
Abstract:
This paper reviews the new developments and new challenges for the nuclear structure studies. It points out that the developments of the nuclear structure today is characterized by the term u Nuclear Structure in Exotic Conditions",the main contents of which are the high spin physics and physics for the nuclei far from the stability line and up to drip lines.All these new developments are solidly ensured by the developments and the constructions of super γ- ray spe ctrometer...
Nuclear Solid State Physics
Xia Yuan-fu
1995, 12(2): 47-51. doi: 10.11804/NuclPhysRev.12.02.047
Abstract:
The study of nuclear solid-state physics provides many new opportunities for nuclear physicists to contribute to the solution of some of the most of the fundamental questions in physics. This paper gives a brief survey of theoretical background and some new results on the microstructure of condensed matter obtained by nuclear methods.The elemental composition of the materials with nuclear methods are presented. The structure and behaviour of the solids under irradiation is discussed.
Some Puzzles in Nucleoastrophysics
Peng Qiu-he
1995, 12(2): 52-60. doi: 10.11804/NuclPhysRev.12.02.052
Abstract:
Some puzzles being anxious to be solved are reviewed in this paper, which include cross sections of the nuclear reactions being important for the stellar evolution, the key problems and difficulties in the theory of both typeⅠa and Ⅱ supernova, and the problem of interstellar medium 26Al.Some research subjects of nucleoastrophysics are also proposed.
Study on some Problems about the Longitudinal Damping Systems
Xu Jian-ming
1995, 12(2): 61-66. doi: 10.11804/NuclPhysRev.12.02.061
Abstract:
Problems about the longitudinal damping systems in which the phase signals are used to control the correcting voltage are studied. The result shows that only either the dt or signal delayed by 1/4 synchrotron oscillation period can be used as the control signal in the longitudinal damping system. If the signal is directly used to control the correcting voltage, the required voltage will be too large to be accepted.
