利用中子背散射技术的高能分辨率观察了在Tc约=180K时有序-无序相变之上对三联苯中苯环取向波动的临界减慢。观察到的弛豫时间 tau c 范围从室温下的约 2*10-11 s 到接近 Tc 的 1.15*10-8 s。
The high-energy resolution of the neutron backscattering technique was used to observe the critical slowing down of the orientational fluctuations of phenyl rings in p-terphenyl above the order-disorder phase transition at Tc approximately=180K. The observed relaxation times tau c range from approximately 2*10-11 s at room temperature up to 1.15*10-8 s close to Tc.
