摘要：

We calculate the flux of x rays produced by low-energy cosmic-ray nuclei in HI regions. We consider electron capture to excited states by cosmic-ray nuclei of heavy elements, followed by cascades down to the ground state. It is found that the electron-capture processes may yield appreciable line intensities in the range 1-10 keV in the galactic plane. © 1969 The American Physical Society.
