## Double 1s shell ionization of Si induced in collisions with 1–3-MeV protons

### In: Physical Review A, 2005, vol. 72, p. 062704

The double 1s ionization of Si induced in collisions with protons was studied by measuring the K x-ray emission of a solid Si target ionized by the impact of 1–3-MeV protons. In order to resolve the hypersatellite contributions corresponding to the radiative decay of the double 1s vacancy state, a high-resolution crystal spectrometer was employed yielding sub-eV energy...
