Abstract:
This article briefly reviewed the EPR paradox and some hypothesises which were stimulated by the EPR paradox to make attempt on correction for quantum theory, such as Bohm-Aharonov hypothesis and local hidden-variable theory, especilly Bell’s inequal...

Abstract:
Light pulse shape, number of photoelectrons per unit energy and obtainable time resolution were studied with BGO scintillator coupled to a XP2020 photomultiplier and compared with the similar measurements on NaI(T1) and ST401 plastic scintillator. Th...

Abstract:
In this paper, We study the polarization effects in large transverse momentum prompt photon production in pp-γx and pp-γx. The asymmetries and the circular polarization of the photon for these processes are calculated. The results are discussed.

Abstract:
Possible proton decay modes in the SU(4)C×SU(2)L×SU(2)R unified gauge model are discussed. There are not proton decays if Higgs particles are not involved in the processes. The characteristics of the decay products make it plausible to distinguish th...

In this paper the Σ-N interaction is studied from the view of the meson exchange. The Σ-N potentials are obtained by means of One-Boson Exchange Potentials and Two-Boson Exchange Potentials. The results are compared with the Λ-N potentials. There may...

A microscopic calculation of the collective spectra of the neutron configurations (closed shells)50 (d5/2g7/2s1/2d3/2h11/12)12 is made based on the Dyson representation of the interacting boson model (IBM). The effective nucleon-nucleon interaction c...

An energy criterion is given for the determination of fission scission point configuration. It is assumed that the splitting of the nucleus occures immediately, if the deformation energy decreases monotonously as the decreasing of the neck radius, wi...

This paper supposes that subquarks perhaps do not obey Fermi statistics. Therefore we discuss other case for Montvay model and get six solutions under preserving asymptotic freedom condition. Four of them lead to SU(7) ×SU(7) grand unification at sub...

We present first results on the properties of Chinese bismuth germanate for detection of photons. 12% light output relative to NaI(T1) with energy resolution AE/E=14%/√E(MeV) was measured for a 23×23×2mm3 crystal. The linearity between the light outp...

Abstract:
We report on-line measurement of the proportional tube counter effeciency plateau. We measured the effeciency plateau of 6 proportional tube counters simultaneously with a TRS-80 micro-computer and CAMAC system.
