Abstract

The photo-absorption cross section of soft X-rays by interstellar gas is calculated using accurate photo-ionization cross sections together with the currently accepted composition of the gas. It is shown that the neon K edge is a distinctive feature of this spectrum even if all the interstellar hydrogen is in molecular form.
