Physical mechanisms and scaling laws of K-shell double photoionization.
We report on the photon energy dependence of the K-shell double photoionization (DPI) of Mg, Al, and Si. The DPI cross sections were derived from high-resolution measurements of x-ray spectra following the radiative decay of the K-shell double vacancy states. Our data evince the relative importance of the final-state electron-electron interaction to the DPI. By comparing the double-to-single K-...
متن کاملLife's Universal Scaling Laws
N 100 years ago, the eminent biologist D'Arcy Thompson began his wonderful book On Growth and Form iCamhridge U. Press, 1917) by quoting Immanue! Kant. The philosopher had observed that "chemistry. .. was a science but not Science . . . for that the criterion of true Science lay in its relation to mathematics." Thompson then declared that, since a "mathematical chemistry" now existed, chemistry...
متن کاملDouble K -shell photoionization and hypersatellite x-ray transitions of 12 Z 23 atoms
Single-photon double K-shell ionization of low-Z neutral atoms in the range 12 Z 23 is investigated. The experimental method was based on measurements of the high-resolution Kα hypersatellite x-ray spectra following the radiative decay of the K-shell double-vacancy states excited by monochromatic synchrotron radiation. The photon energy dependence of the double K-shell ionization was measured o...
متن کاملDouble K-shell photoionization of low-Z atoms and He-like ions
We report on the investigation of the photon energy dependence of double 1s photoionization of light atoms and compare the cross sections for hollow atom and He-like ion production. Measurements of the Kα hypersatellite x-ray spectra of Mg, Al, and Si were carried out using the Fribourg high-resolution x-ray spectrometer installed at the ID21 and ID26 beam lines at the ESRF. The double-to-singl...
