Correction of Relativistic Center-of-Mass Vector on Electric Polarizability of Pion Meson

We estimate the correction of relativistic center-of-mass vector on electric polarizability of an equal-mass quark-antiquark system numerically. Effect on the system confined by different interactive potentials is analysed. A great improvement for the electric polarizability of pion meson is obtained.

Measurement of Integrated Stokes Parameters for He 3 ^3p State Excited by Spin-Polarized Electrons

综合司烧参数 P-i (i = 1， 2,3 ) 为他 3 P-3 -】 2 S-3 (1 )(388.9nm ) 在来自扎根的状态的刺激到以后的转变 3 (3 ) 由一根极化 transverselyspin 的电子横梁的 p 状态在近的阀值精力被测量区域。试验性的结果被介绍。线性极化的 P-2 在事件精力范围上与零一致，提供为联合机制的 LS 的证据 3 (3 ) p 状态。测量圆形的极化 P-3 是非零，显示在极化 thespin 的电子原子碰撞过程的强壮的电子电子交换效果。
