RELATIVISTIC EQUAL-TIME EQUATION (Ⅰ)

1981, 5(4): 393-404.
Abstract:
For a given Bethe-Salpeter equation an unique definite rearrangement of its irreducible kernel is obtained. Using this new kernel the equal-time wave function and equal-tune seattering amplitude satisfy closed equations respectively. Including no unp...
STRATON MASSES AND CABIBBO ANGLES
Xu DE-ZHI
1981, 5(4): 405-411.
Abstract:
In the SUL(2)×SUR(2)×U(1) local gauge theory, we discuss the general form of the interaction Lagrangian between the stratons and the Higgs particles, which is invarant with respect to the discrete transformation eia. From this Lagrangian we obtain a ...
THE PROCESS e++e-→π+q+q IN QUANTUM CHROMODYNAMICS
HUANG CHAO-SHANG, DAI YUAN-BEN
1981, 5(4): 412-416.
Abstract:
In this paper we investigate the behavior of the B-S wave function as the squared momentum on one leg becomes infinte while the squared momentum on the other leg remians fixed by using the property of asymptotic freedom in QCD. Using the obtained wav...
GLUE BAG MODEL AND MASS SPECTRA OF HADRONS
YIN PENG-CHENG, ZHOU GU-SHENG, WANG JIA-ZHU, WANG ZI
1981, 5(4): 417-428.
Abstract:
On the basis of glue-bag model discussed in previous article, we calculate mass spectra of hadrons, and find that the dependence of the surface energy is sensitive to the state of motion of quarks. We compare the theoretical results with the experime...
BOSE CONDENSATION OF SU(2) HIGGS FIELDS AND THE ELECTRON MASS IN WEINBERG-SALAM MODEL
NI GUANG-JIONG, SU RU-KENG, CHEN SU-QING
1981, 5(4): 429-440.
Abstract:
The concept of Bose Condensation of Higgs fields is applied to SU(2) Higgs φ4 model. It is proved that under the selfinteractions between Higgs fields, when the sum of condensation densities of charged complex fields and neutral complex fieldsremains...
THE “UNIRARY ENERGY BAND” STRUCTURE IN THE BARYON-ANTIBARYON SYSTEN
WANG WEI-WEI, ZHANG YU-SHUN, LI YANG-GUO, CHEN XIAO-TIAN, RUAN TU-NAN
1981, 5(4): 441-451.
Abstract:
In the present paper a picture of the baryon-antibaryon system is proposed. If proton, neutron and A hyperon with spin 1/2 form the SU(6) basic particles, then the baryon-antibaryon system must be classified by the SU(6) group (It can be classified i...
ON THE ANALYSIS OF SEGMENTED RING OF PERMANENT MAGNET MULTIPOLE FIELDS
LIU MAO-SAN, CHEN REN-HUAI, WU WEN-TAI, LI SHU-ZHEN
1981, 5(4): 452-457.
Abstract:
Assuming uniform magnetization of individual magnet pieces, a three dimensional analytical expression for the magnetic field of a newly developed multipole structure of the permanent magnet segmented ring is derived.
J PARTICLE-NUCLEUS SCATTEIUNG
ZHANG YU-SHUN, LIU XIAN-HUI, LI YANG-GUO, HE ZUO-XIU
1981, 5(4): 458-464.
Abstract:
Basing on the J particle-nucleus scattering, the J particle-nucleon scattering strength is estimated. The calculation result shows that for the scattering on light nucleus, there is no second diffractive maximum, but on heavy nucleus, there is a seco...
SCATTERING AMPLITUDE WITH LARGE MOMENTUM TRANSFER CALCULATED FROM THE BAKAMJIAN-THOMAS EQUATION AND THE REPULSIVE CORE OF NUCLEAR FORCE
PAN JI-ZHI, WANG WEI-WEI, ZHAO WEI-QIN, BAO CHENG-GUANG
1981, 5(4): 465-471.
Abstract:
Using Born expansion of Elkonal wave function, a scattering amplitude with large momentum transfer is obtained for B-T equation. Comparing with the experimental data of p-p scattering at s
THE VERTICAL INTENSITY OF THE ANTIPROT ON AT THE ATOMOSPHERIC DEPTH x=700g/cm2
QIN KE-YU
1981, 5(4): 472-476.
Abstract:
At the atmospheric depth x=700 g/cm2, the vertical intensity of the antiproton is calculated by using the data of the high energy accelerators. The comparison with the experimental result shows that up to energy E0=105 GeV of the primary cosmic ray, ...
PROPAGATION OF COSMIC RAY ELECTRONS IN THE GALAXY
ZHANG HE-QI
1981, 5(4): 477-483.
Abstract:
In this paper, a non-steady state solution for the propagation equation is obtained by means of the Green function. We consider several models of the source function in the calculation. The electron spectrum derived from these kinds of source functio...
HIGH ENERGY PRIMARY ELECTRON SPECTRUM AND DIFFUSION X-RAY SOURCE
Xu CHUN-XLAN, ZHANG HE-QI
1981, 5(4): 484-488.
Abstract:
Non-steady state electron spectrum in interstellar medium is investigated by using the model of isotropic diffusion of primary cosmic electrons originated from explosion of supernovae. The diffusion coefficient was determined semi-experientially acco...
THE MOMENTUM DISTRIBUTION OF THE NUCLEAR CLUSTER FOR 6,7Li NUCLEI
HAN WEN-SHU, LU ZHAO-QI, ZHUANG FEI, ZHENG YU-MING
1981, 5(4): 489-492.
Abstract:
In this paper, the momentum distribution of the nuclear cluster, which depended on the distance between the centres of wells, is derived by using 6,7Li nuclear cluster structure wave functions taken from the previous paper(1). It is in a good agreeme...
TWO-NUCLEON TRANSFER REACTIONS ON DEFORMED NUCLEI
WU CHONG-SHI, ZENG JIN-YIAN
1981, 5(4): 493-502.
Abstract:
The spectroscopic factors of two-nucleon transfer reactions between even tungsten nuclei have been calculated with the particle number conservation method for treating the pairing force. The gross features of the calculated spectroscopic factors are ...
THE GENERATOR COORDINATE METHOD FOR THE COUPLING BETWEEN THE PAIRING AND SURFACE VIBRATIONS
Fu DE-JI, XIA KE-DING
1981, 5(4): 503-507.
Abstract:
The interplay between the pairing and surface vibrations is investigated within the framework of the generator coordinate method which treats both modes of collective motions on the same footing, By extending subspace we esimate the coupling effect o...
TO ANALYSE THE PROPERTY SUPERBAND BY USING 2Δ
GAO YUAN-YI
1981, 5(4): 508-512.
Abstract:
Using two-quasipartiele energy the rotational alignment angular momentum is calculated, the property of the superband of some nuclei is also analysed qualitatively.

Gu JIN-NAN
1981, 5(4): 513-517.
Abstract:
An effective rotation-alignment angular momentum J is introduced. The sence for i(ω) and J is discussed, and the yrast band for even-even rare earth nuclei is analysed in a systematic way.
A COMPLEMENTARY ANALYSIS OF THE EXPERIMENTAL DATA FOR REACTION 12C+209Bi AT THE INCIDENT ENERGIES SLIGHTLY ABOVE THE COULOMB BARRIER
Xu SHU-WEI
1981, 5(4): 518-520.
Abstract:
Using partial fusion mechanism, a possible explaination why the probabilities of 6Be-transfer for reaction 12C+209Bi at the incident energies slightly above the Coulomb barrier are large is given, while the probabilities of α-transfer is almost negli...
