摘　　要：用程序降温法生长了SrFCl:Eu^(2+)晶体,并测量了它的电子自旋共振谱。应用最小二乘法拟合技术对g因子及自旋哈密顿参数进行了精确拟合。报道了各向异性的g因子及有关自旋哈密顿参量。发现并归属了Eu^(2+)的高阶禁阻跃迁。The SrFCl:Eu2+ single crystal was grown by programmed cooling method, and its electron spin resonance (ESR) spectra were recorded. The g factors and ESR parameters were simulated with the Least-Square Fitting Method. The anisotropic g factors and related spin Hamiltonian parameters were reported. High-order forbbiden transition of Eu2+ in SrFCl:Eu2+ crystal were observed and assigned according to the calculation results.
