Growth of an ultrasoft X-ray spectroscopy organic crystal dioctadecyl adipate (OAO)

A high-purity dioctadecyl adipate (OAO) single crystal, of dimensions 30 * 20 * 0.1 mm³, can be grown over a period of fourteen days using the appropriate method. Diffraction studies on the crystal have indicated the suitability of this system in the dispersing of ultrasoft X-rays in X-ray spectroscopy; large 2d spacing (94.85 AA), high resolution and reflection properties. The OAO crystal was employed in an X-ray spectrometer to obtain the spectra of pure boron at the B K-edge and diamond at the C K-edge; the results from the experiments clarify the suitability of an OAO single crystal as an ultrasoft X-ray dispersant.
