The parameters in this table are used in equation (<a href="http://iopscience.iop.org/0953-4075/46/14/145601/article#jpb458169eqn05" target="_blank">5</a>). Amplitudes <em>A<sub>i</sub></em>, centroids <em>C<sub>i</sub></em> and widths <em>W<sub>i</sub></em> of individual components were obtained from a fit on the intensity versus detector position axis. The detector position axis was transformed to an absolute energy scale via the calibration procedure. The Gaussian width σ was 0.805(25) eV. The background was 749(24) counts.</p> <p><strong>Abstract</strong></p> <p>Transition metals have Kα and Kβ characteristic radiation possessing complex asymmetric spectral profiles. Instrumental broadening normally encountered in x-ray experiments shifts features of profiles used for calibration, such as peak energy, by many times the quoted accuracies. We measure and characterize the titanium Kβ spectral profile. The peak energy of the titanium Kβ spectral profile is found to be 4931.966 ± 0.022 eV prior to instrumental broadening. This 4.5 ppm result decreases the uncertainty over the past literature by a factor of 2.6 and is 2.4 standard deviations from the previous standard. The spectrum is analysed and the resolution-free lineshape is extracted and listed for use in other experiments. We also incorporate improvement in analysis applied to earlier results for V Kβ.</p> 2013-06-13 00:00:00 energy scale profile detector position axis experiment ev width calibration Abstract Transition metals peak energy Atomic Physics Molecular Physics
