本文详细研究了纯IaB型金刚石中的空穴，其中前者是随机分布的，与{001}变形片晶无关。从电子衍射图中看到的额外的，辅助斑点的证据，从体积的晶体含有空洞，并在空洞图像中的莫尔条纹，表明一个结晶相与四元晶胞作为空洞内容。在这方面，这些空隙不同于与转化的血小板相关的空隙，早期的工作人员检测到面心立方结构。否则，在这两种情况下，包含空隙石材料的原子种类显然是相同的，因为在这种情况下，电子能量损失谱同样指示出给出强氮信号的相。
Abstract Voidites in purely type IaB diamonds, in which the former are found in random distributions not associated with transformed {001} platelets, have been studied in detail. The evidence from extra, subsidiary spots seen in the electron diffraction patterns from volumes of crystal containing voidites, and from Moire fringes in voidite images, indicates a crystalline phase with a tetragonal unit cell as the voidite content. In this respect, these voidites differ from those seen in association with transformed platelets, in which earlier workers detected face-centred cubic structures. Otherwise, the atomic species comprising the voidite material is apparently the same in the two cases, since electron energy-loss spectroscopy in the present case indicates, likewise, a phase that gives a strong nitrogen signal.
