Abstract

It is shown that it is possible to perform combined X-ray and neutron single-crystal studies in the same diamond anvil cell (DAC). A modified Merrill-Bassett DAC equipped with an inflatable membrane filled with He gas has been developed. It can be used on laboratory X-ray and synchrotron diffractometers as well as on neutron instruments. The data processing procedures and a joint structural refinement of the high-pressure synchrotron and neutron single-crystal data are presented and discussed for the first time.

摘要

结果表明，在同一个金刚石对顶砧（DAC）中进行X射线和中子单晶联合研究是可行的。已开发出一种改进的配备充有氦气的可充气膜的梅里尔 - 巴塞特DAC。它可用于实验室X射线和同步加速器衍射仪以及中子仪器。首次给出并讨论了高压同步加速器和中子单晶数据的数据处理程序及联合结构精修。
