我们提出的证据，在冲击压缩铋使用SPEDX X射线衍射技术的相变。实验是在英国迪科RAL的中央激光设备上进行的。我们观察到来自Bi-V的（110）bcc峰的衍射，并且从其计算的晶格参数确定压力为约17 GPa。在进一步压缩（更高的激光强度）时，没有观察到来自固相的进一步衍射。铋的冲击熔化被认为发生在18和27 GPa之间。衍射结果在较低的压力作为延迟时间的函数。
We present evidence for phase transitions in shock-compressed bismuth using the SPEDX x-ray diffraction technique. Experiments were performed on the Vulcan laser at the Central Laser Facility, RAL, Didcot, UK. We observed diffraction from the (110) bcc peak of Bi-V, and from its calculated lattice parameter the pressure was determined to be approximately 17 GPa. Upon further compression (higher laser intensities), no further diffraction from solid phases was observed. Shock melting of bismuth is thought to occur between 18 and 27 GPa. Diffraction results at lower pressures as a function of delay time are also presented.
