Experimental method for spin-parity analysis of j/ ψ radiative decay products J/φ辐射衰变产物自旋宇称分析的实验方法
In this paper we discuss the production and decay of the glueball candidate θ/ f_2,( 1720) in the J/ ψ radiative decay. 本文讨论了J/φ辐射衰变中胶子球候选者θ/f2(1720)的产生及其衰变。
The results show that it is possible to determine the radiative and non-radiative decay quantatively by comparing measurements taken with transparent and blackened cavities. 测量结果确定两种衰减方式,辐射和无辐射定量结果,并且发现表面粗糙度对衰减方式有影响。

An estimation of the contribution from the vector meson intermediate state to the width of the radiative decay of a heavy vector meson into Higgs particle is given. 本文估计了矢量介子中间态对由重夸克组成的重矢量介子辐射衰变到Higgs粒子的宽度的贡献。
Radiative decay of x_c and hadronic production of the new particles Xc辐射衰变和新粒子强产生
The rest-mass effects of the muon's neutrino are discussed. The influence on the two processes-the radiative decay of π mesons and the muon-electron annihilation-in which these effects are exhibited appreciably is analysed in detail. 本文讨论了μ中微子的静质量在各种过程中的效应,特别分析了两个此效应表现得明显的过程,μ介子与电子的湮没和π辐射衰变。
Based on the study of this J/ ψ radiative decay channel, it provides us some useful data for the selection of crystal BGO or CsI of electromagnetic calorimeter and for the selection of magnetic field intensity. 基于所研究的衰变道,为BESⅢ电磁量能器晶体BGO和CsI的选择及磁场强度的选择提供了数据。
The radiative decay of an ω particle ω粒子的辐射衰变
The fluorescence quantum yields and lifetimes, and radiative and non-radiative decay rate constants are depended on the polarity of vinyl polymers. DAMC在聚合物介质中荧光量子产率和荧光寿命决定于介质的极性,辐射失活速率常数与非辐射失活速率常数也与此相关。
The change of φ f in different media was consistent with the change of radiative and non-radiative decay rate constants. 在各种介质中,φf与辐射和非辐射失活速率常数的变化相一致。
This article calculates the radiative decay process π+ → e++ v+ r of the π+ meson, by employing the field-current identity of the axial vector current which may be deduced from field algebra theory or the quantum theory of composite fields. 本文应用由复合场场论或场代数导出的轴矢流的场流恒等式计算了π介子的辐射衰变π~+→e~++ν+γ过程。
The results show that this possibility is existent both in J/ ψ radiative decay and hadronic decay processes. 结果表明,对于J/ψ的辐射衰变过程和强子衰变过程,这种可能性都是存在的。
