| 摘 要： | 本文采用时间微分扰动角关联方法,测量了80—422K温度范围内~(111)Cd在In_(0.95)Ag_(0.043)Ga_(0.005)合金中的四极相互作用随温度的变化,进而导出晶格电场梯度的温度变化。在In_(0.95)Ag_(0.043)Ga_(0.005)合金中,晶格电场梯度的温度变化遵从T~(3/2)定律:V_(zz)(T)=V_(zz)(0)(1—BT~(3/2)),斜率B=7.48(47)·10~(-5)K~(-3/2)。在80、298和422K的电场梯度分布宽分别为0.1147(259)、0.0924(340)和1.344(175)。表明在液氮温度和室温时,合金的晶格结构特性较好,温度升高,晶格结构特性变坏。

| Abstract: | The temperature dependence of the quadrupole interaction of 111Cd in In0 95 Ag0 045 Ga0.005 alloy is determined by the time differential perturbed angular correlation (TDPAC) method from 80 to 422K. The electric field gradients produced by the lattice in the alloy are derived. The temperature dependence of the electric field gradient follows the T3/2law: Vzz(T) =Vzz(O) (1-B3/2) with a slop B= 7. 48(47). 10-5K-3/2. The FWHM's of the electric field gradient are 0.1147(259), 0.0924(340) and 1.344 (175) at 80, 298 and 422 K, respectively. This indicates that the characteristics of the lattice structure of the alloy are better at 80 and 298 K than at 422K. |
