宝石级锆石中Gd^(3+)的电子顺磁共振

ELECTRON PARAMAGNETIC RESONANCE IN GEM QUALITY ZIRCON

本文测量了含有微量Gd^(3+)杂质并具有四角对称结构的天然锆石单晶的电子顺磁共振谱。用最小二乘法拟合技术严格地计算了精细结构参数。Gd的奇数同位素的超精细结构清晰可辨,并给出了超精细耦合常数的一级近似值。

The electron paramagnetic resonance spectra of the natural single crystal of the tetragonal structure zircon containing impurity Gd3+ have been measured. The fine structure parameters were calculated using a least-squares fitting procedure. The hyperfine structure for odd isotopes 155 Gd and157Gd was clearly resolved, and the values of the hyperfine coupling constant to first order were given.
