同位旋

Since ρ〓,ω are neutral vector mesons, the G-parity breaking is caused by the isospin symmetry breaking. We study the form factor of π, F〓, which is an important observable related to ρ〓-ω mixing problem.

在这个问题中，由于ρ〓，ω都是中性矢量介子，因此G宇称的破坏主要是由同位旋对称性破缺引起，在讨论这个问题时我们首先讨论了对ρ〓-ω问题有重要意义的π介子的电磁形状因子F〓。

Our paper is organized as follows: lIn the quarkonium-quarkonium mixing scheme, we predict the mass of isoscalar of the 3~1S_0 nonet(1900±12MeV).

在这里，我们主要做了三方面的工作：1在介子—介子混合框架下，估计了3~1S_0介子九重态中同位旋标量态？

The development of new experiments for neutron halo is briefly described, while the isospin and energy dependence of Glauber theory and its importance in describing halo nuclei -nucleus scattering are discussed.

简要介绍了中子晕和质子晕研究的最新实验进展，同时，讨论了近年来发展的同位旋，能量有关的具有晕核结构的 Glauber理论及它在描述晕核与核散射时的重要性。

Nucleoneffective interactions in the RMF are extracted by reproducing the properties ofsymmetric and asymmetric nuclear matter in the DBHF calculation. It is found thatthe properties of finite nuclei are depicted satisfactorily by those effective interactions.

用DBHF计算的对称和不对称核物质中核子自能或核子平均结合能在RMF下得到的同位旋相关的核子有效相互作用可以很好地描述有限核的性质。

With these few parameters we can describe a large class of the radiative decay processes and the baryon magnetic moments.

基于这些积极的结果，我们在这一框架内研究了同位旋对称性破缺效应。

We include the electromagnetic effects consistently in the QCD sum rule approach to keep the final sum rule gauge invariant. Then we study the role of electromagnetic effects in the isospin symmetry breakings of the system.

我们把电磁相互作用自洽地包括进来使最后的求和规则是规范不变的，然后研究电磁效应在体系的同位旋对称性破缺中的作用。

The study of nuclear matter at extreme isospin is one of hot topics in present nuclear physics.

极端同位旋条件下核物质性质的研究是国际上核物理研究前沿中的一个热点。

The investigation of single-particle levels shows that the shell structure is deformed and isospin dependent.

对单粒子能级的计算和分析表明超重核的壳结构是形变和同位旋相关的。

Calculations show that the isospin effects on particle emission have a strong dependence on the angular momentum.

高的角动量不但弱化了同位旋对粒子蒸发的影响，而且也降低了核耗散对粒子发射的影响。
