摘要:

冰Ih,从冰下湖沃斯托克吸积冰层(3621米深)提取的单晶进行了研究,通过扩散X射线散射和非弹性X射线散射。漫散射被确定为主要是非弹性和合理化的从头计算的有序冰XI近似的框架。与蒙特卡洛建模,我们的数据允许重新考虑以前可用的重冰的中子漫散射数据的热漫散射和静态无序贡献的总和。

英文摘要:

Single crystals of ice Ih, extracted from the subglacial Lake Vostok accretion ice layer (3621 m depth) were investigated by means of diffuse x-ray scattering and inelastic x-ray scattering. The diffuse scattering was identified as mainly inelastic and rationalized in the frame of ab initio calculations for the ordered ice XI approximant. Together with Monte-Carlo modelling our data allowed reconsidering previously available neutron diffuse scattering data of heavy ice as the sum of thermal diffuse scattering and static disorder contribution.
