【摘要】 本文以Tanabe-Sugano矩阵为基础,通过分析和计算发现,⁴Υ₂和²E零声子线之间的间隔△与参数D_q、B、C和△E_?（斯托克斯频移）之间有简单的线性关系.举例说明了此关系式的应用,并对P.T.Kenyon晶场强度判据作了推导,指出了其在应用上的局限性.更多还原

【Abstract】 The simple linear relation between Δ (the gap between 4T2 and 2E zero-phonon lines) and parameters Dq, B. C and ΔE, (Stoke’s shift), was discovered by analysis and calculations on the basis of Tanabe-Sugano matrices. The applicability of the relationship was explained on sone examples. The crystal-field strength criterion made by P. T. Kenyon was deduced and its limitation in the application was pointed out.更多还原
