Parametric X-Ray Study from Textured Molybdenum Polycrystal

We performed a systematic study on Parametric X-ray radiation from a textured polycrystalline molybdenum target at a 150-MeV electron ring. The measurements were conducted at three observation angles (11.27, 25.89, and 179.85 degrees). The spectral data shows that the spectrum has a unique characterestics: its peak energies depend mainly on the observation angles, its width is much wider than that with the monocrystal case, and its intensities are sometimes comparable to the charactestics K alpha of Mo. The observed properties are related to the texture of the polycrystal.
