TDPAC (Time Differential Perturbed Angular Correlations) Study of Liquid and Amorphous Se sub (1-x)Te sub x Alloys.
Abstract
A time differential perturbed angular correlation study on several liquid and amorphous splat-quenched Se sub (1-x)Te sub x alloys was performed using dilute 111Cd as the tracer. The liquid spectra exhibits an attenuation factor, Lambda 22, consistent with the motional narrowing approximation. The attenuation factor is proportional to the motional correlation time tc, multiplied by the average square electric quadrupole frequency, NUQ2. NU sub Q has been characterized in amorphous splat-quenched Se and Te, allowing tc to be computed for these two liquids from the measured Lambda 22. Spectra in both amorphous Se and Te arise from two distinguishable sites with quadrupole frequencies similar to the sites in compounds of Se or Te with In.
