RESEARCH ON SOME CHARACTERISTICS AND IMPROVEMENTS OF A 70cm STREAMER CHAMBER
The Second Experimental Division
1983, 7(3): 273-284.
Abstract:
In this paper the influence of various proportion of Ne-He gases and the time delay on the quality of streamer tracks has been studied. The diameterand density of streamers under these mixed-gas conditions have been measured.
The time resolution of th...

WANG Man, LI Jin, LI Pei-Qin, CHEN Xian-Neng, CHEN Li-Jun, JIANG Chun-Hua, XIA Xiao-Mi, LU Wei-Da, QUE You-Kun, LAN Yuan-Fen, LU Chang-Guo, CUI Xiang-Zong
1983, 7(3): 294-300.
Abstract:
In this paper, a multi-strip scintillation counter hodoscope and a small on-line system are described. The hodoscope is a 4×4 array of scin tillation strip counter, each of which consists of a plastic scintillation strip of type NE104 with the dimens...
THE BEHAVIOURS OF F2ep(X, Q2)-F2en(X, Q2) AND THE SCALE-BREAKING PARAMETER
SHEN Qi-Xing, WU Ji-Min, LU Jing-Xian, ZHAO Pei-Ying
1983, 7(3): 301-308.
Abstract:

The scale-breaking parameter F2ep(x, Q2) of non-singlet component F2ep-F2en and some other quantities in the electro-production process are discussed by usinb the analytic expression for the distribution function of valence quarks in ha.drons up ...

THE QCD BEHAVIOURS OF THE XF3 (X, Q2) UP TO THE LEADING LOG IN THE NEUTRINO DEEPINELASTIC PROCESSES
SHEN Qi-Xing, WU Ji-Min, LU Jing-Xian, ZHAO Pei-Ying
1983, 7(3): 309-315.
Abstract:
The QCD behaviours of the structure functions xF3 in the neutrino deep-inelastic processes are discussed by using the analytic expression for the distribution function of valence quarks in hadrons up to the leading log approximation given by a previo...
A DYNAMICAL MODEL FOR THE GLUON DISTRIBUTION FUNCTION
ZHU Wei, SHEN Jian-Guo
1983, 7(3): 316-322.
Abstract:
In this paper the forms of the gluon distribution function at different Q2 are discussed with the aid of the three-quarks model associated with dynamical calculations of QCD (the LLA approximation). The Buras-Gaemers parametrization is improved and t...
BOUND STATE WAVEFUNCTIONS AND ANOMALOUS MAGNETIC MOMENTS OF LEPTONS
ZHAO Guang-Da
1983, 7(3): 323-332.
Abstract:
Assuming that leptons are composed of a heavy fermion and a heavy scalar boson and using Bethe-Salpeter equation, we conclude that in the non-relativistic limit the radius and , in particular, the anomalous magnetic moment of leptons can be sufficien...
ONE LOOP CORRECTIONS OF THE FERMION MASSES AND THE CP-VIOLATION CALCULATIONS OF THE STRONG AND WEAK INTERACTIONS
LI Chong-Sheng, HU Shi-Ke
1983, 7(3): 333-341.
Abstract:
In a renormalizable gauge theory of spontaneously broken symmetry, using the path integral method, we derive a formula for calculating the one loop corrections of the effective potentials in the general case and the expressions for the one loop corre...
A FOLDED DIAGRAM METHOD FOR DERIVING AN ENERGY-INDEPENDENT NUCLEON-NUCLEON (N-N) POTENTIAL FROM MESON EXCHANGES (Ⅱ) APPLICATION
LI Guang-Lie
1983, 7(3): 342-345.
Abstract:
Using the method proposed in the paper (Ⅰ)[1], we investigate the potential between two neutral scalar nucleons by exchanging neutral scalar mesons. The results show that the contribution of mesonic folded diagrams to this potential is not negligible...
THE TIME RESPONSE OF THE FERRITE LOADED CAVITY AND STABILITY OF BIAS AUTOTUNING SYSTEM
YAN Tai-Xuan, SUN Li-Bo
1983, 7(3): 346-354.
Abstract:
A state space model is described, the time response of ferrite loaded cavity is proposed and a new digital measuring method devised.
Results of actual measurement on model cavity are given. On these bases the stability of stationary state of bias auto...
RADIATIVE CAPTURE IN THE INELASTIC CHANNEL OF THE COMPOUND NUCLEUS
LIU Jian-Feng, HUO Yu-Kun
1983, 7(3): 355-360.
Abstract:
In this paper, the radiative capture in the inelastic channel of the compound nucleus is discussed.
Starting from the S-matrix theory, the calculation formular for this situation is derived. Then connected with the optical model and Hauser-Feshbach's ...
A METHOD OF DATA ANALYSIS OF THE MAGNETIC SPECTROMETER
SHEN Wen-Qing
1983, 7(3): 361-369.
Abstract:
A method of data analysis of the magnetic spectrometer with heavy ion is discussed. The determination of the charge state, the atomic number, the atomic mass and the energy of reaction products are described. The paper also deals with the soft ware c...
MONTE CARLO CALCULATION OF THE EFFICIENCIES OF THE LEAD GLASS DETECTORS FOR HIGH-ENERGY GAMMA RAYS
ZHANG Gui-Shan, ZHANG Huan-Qiao
1983, 7(3): 370-378.
Abstract:
In this paper, the electromagnetic shower processes occured in the lead glass detector are simulated by the Monte Carlo method, the light collection effects being taken into account. The primary energy of gamma ray is from 8 to 30 MeV. The detected e...
INFLUENCE OF SHELL STRUCTURE ON DEEP INELASTIC COLLISIONS
WU En-Chiu
1983, 7(3): 379-394.
Abstract:
A kinematically complete study of the symmetric systems 154Sm+154Sm and 144Sm+144Sm has been performed at energies 30% in excess of the interaction barrier. They have been chosen because of their different internal structure: 144Sm has a closed N=82 ...
DATA PROCESSOR FOR THE MAGNET WITH CURVATURE
