强磁场中铷原子与惰性气体原子核自旋交换理论

THFORY OF SPIN-EXCHANGE BETWEEN OPTICALLY PUMPED RUBIDIUM AND NOBLE GAS NUCLEI AT HIGH MAGNETIC FIELD

我们计算了铷价电子与惰性气体原子核自旋交换截面,结果表明:理论计算值与实验结果符合较好,并且由于电子交换作用,自旋交换截面值被大大增强了。对He^3,Ne^(21),Kr^(83),Xe^(129)和^(131)Xe,自旋交换截面值分别为:5.5×10^(-24),1.3×10^(-23),1.2×10^(-21),7.6×10^(-21)和3.4×10^(-21)cm^2。

Cross sections for spin-exchange between alkali valence electrons and noble gas nucl have been calculated at high magnetic field. Results show that ualues of cross sections ere geed agree with experimental data, and values of cross sections are greatly magified as a result of electron exchange. For He^3, Ne_2~1, Kr^(83), Xe^(129). and Xe^(131) Cross Sections for spin-exchange are 5.5×10^(-24), 1.3×10^(-23);1.2×10^(-12), 7.6×10^(-21) and 3.4×10^(-21)cm^2.
