High order neutron components from Ge(lll) reflection have been measured in the region of 5—22 meV using time-of-flight method at the heavy water reactor in Beijing. The measured results have been compared with theoretical calculation and a satisfactory agreement is obtained. The results show that Ge(111) reflection suffers from a serious order contaminations below 20 meV.
