Abstract

摘要 本文采用LГ表象,考虑到不同组态间的相互作用(立方场,三角场与自旋轨道作用),计算了红宝石中锐线B,S与R线的能级及其分裂和基态的分裂。所得结果是B线与R线跟实验较符合,基态的分裂较实验值小,这可能是更高能级的三角场与自旋轨道的微扰作用所引起的。 Abstract By means of the LT representation the author calculated the energy levels and the splittings of sharp lines in ruby. The interaction between various configurations has been taken into account. The splittings of energy levels of R and B lines so obtained agree well with experimental results. But the splitting of ground state comes out too small to be compared with experiment. If may be attributed to the perturbation of the higher energy levels. . 作者及机构信息 谭维翰 1. 中国科学院 Authors and contacts TAN WEI-HAN 1. 中国科学院 参考文献 [1] 施引文献

CALCULATION OF THE DIRECT PROCESS OF SPIN-LATTICE RELAXATION IN RUBY

HUANG WU-HAN, LIN FU-CHENG, LAU CHIE-HUNG

摘要 本文计算了在低温、低浓度下红宝石基态自旋-晶格弛豫的直接过程。应用强场耦合表象中基态的二级微扰波函数,在θ=90°,脉冲饱和法测量条件下,计算了基态四能级之间的无辐射跃迁几率。然后,用求解粒子数方程的方法,计算1.4°K的自旋-晶格弛豫时间。计算结果与Pace等人的实验结果较好地符合。 Abstract The direct process of spin-lattice relaxation in the ground state of ruby of low concentration is calculated at low temperature. The nonradiative transition probabilities within the four ground sub-levels are calculated by aid of second-order wave functions obtained in the strong-field coupling scheme. Under the measured condition of impulse saturation at θ=90°, the spin-lattice relaxation time at 1.4°K is obtained by solving the rate equations. The calculated result conforms satisfactorily to the experimental data given by Pace et al. 作者及机构信息 黄武汉, 林福成, 楼祺洪 1. 中国科学院 Authors and contacts HUANG WU-HAN, LIN FU-CHENG, LAU CHIE-HUNG 1. 中国科学院 参考文献 [1] 施引文献
