红宝石R＇、B线及U、Y带压力移位的理论计算

THEORETICAL CSLCULATIONS OF PRESSURE-INDUCED SHIFTS OF THE R' AND B LINES AND THE U AND Y BROAD BANDS OF THE SPECTRA FOR RUBY

基于电子径向波函数在加压下扩展的概念，把Ｂ、Ｃ、Ｄｑ、ξ等参量表示成线性压缩ｋ＼的函数，并进一步考虑三角场作用，理论计算了红宝石Ｒ＇、Ｂ线及Ｕ、Ｙ带的光谱压力移位，结果与实验数据符合很好。

n the basis of the concept of expansion of the electron radial wave function under compression, using B.C.D,and as functions of the liner compression ratio , taking further into account the effect of trigonal field, we calculated theoretically the pressureinduced shifts of the R'and B lines and the U and Y broad bands of the spectra for ruby.The results agreed well with the experimental data.
