High l state population in O sup 7+ produced in ion-solid collisions

PDF Version Also Available for Download.

Description

The high {ell}-state population of fast ions excited in ion-solid interactions is very different from {ell}-state populations produced under single collision conditions. A study of the population dynamics of electronic excitation and transport within the framework of a classical transport theory for O{sup 2+} (2 MeV/u) ions traversing carbon foils shows food agreement with experimental results from delayed photon emission spectroscopy. We investigate the dependence of the characteristic exponent for the power-law decay of delayed Ly{alpha} and Ly{beta} radiation on the initial n,{ell} distribution. From our simulations we find evidence that the very high {ell}-state populations produced in ion-solid collision ... continued below

Description

The high {ell}-state population of fast ions excited in ion-solid interactions is very different from {ell}-state populations produced under single collision conditions. A study of the population dynamics of electronic excitation and transport within the framework of a classical transport theory for O{sup 2+} (2 MeV/u) ions traversing carbon foils shows food agreement with experimental results from delayed photon emission spectroscopy. We investigate the dependence of the characteristic exponent for the power-law decay of delayed Ly{alpha} and Ly{beta} radiation on the initial n,{ell} distribution. From our simulations we find evidence that the very high {ell}-state populations produced in ion-solid collision are the consequence of a high-{ell} state diffusion under the influence of multiple inelastic and elastic collisions in the bulk of the solid. 15 refs., 4 figs.
