Spatially resolved characterization of Xe ion irradiated LiF crystals using static field gradient NMR

Abstract:
Spatially resolved (19)F and (7)Li nuclear magnetic resonance (NMR) spin-lattice relaxation rates have been measured in LiF crystals irradiated with 1.44 GeV Xe ions at fluences from 10(10) to 10(12) ions cm(-2). In addition, the F-centre concentration has been measured by optical absorption spectroscopy and the concentration of paramagnetic centres by electron paramagnetic resonance (EPR). Within the ion range, the relaxation rate turns out to increase linearly with the concentration of paramagnetic centres but super-linearly with the F-centre concentration. Beyond the ion range, the relaxation rate is still significantly enhanced compared to non-irradiated LiF.

Diffraction
Diffraction is the change in the direction of travel experienced by an electromagnetic wave when it encounters a physical barrier whose dimensions are comparable to those of the wavelength of the light. X-rays are electromagnetic radiation with wavelengths about as long as the distance between neighboring...
X-ray Diffraction of Biological Samples
According to Bragg's law, when X-rays strike the sample positioned on a stage, the rays are scattered by the electron clouds around the sample atoms. The X-ray diffraction or scattering is caused by constructive interference of the X-ray waves that reflect off the internal crystal...
