Abstract
Electron excitation collision strengths for fine-structure transitions 3s23p5-3s3p6, 3s23p5-3s23p43d and 3s3p6-3s23p43d in Fe X, are calculated using a 180-level Breit-Pauli R-matrix calculation containing the above levels together with those from 3s3p53d and 3s23p33d2 configurations. The collision strength is averaged over a Maxwellian velocity distribution to obtain the effective fine-structure collision strengths as a function of electron temperature from $\log T({\rm K})=5.4-7.0$. We show that low-energy resonances enhance the effective collision strength, with significant effects on level populations.

What is OpenURL?

The OpenURL standard is a protocol for transmission of metadata describing the resource that you wish to access. An OpenURL link contains article metadata and directs it to the OpenURL server of your choice. The OpenURL server can provide access to the resource and also offer complementary services (specific search engine, export of references...). The OpenURL link can be generated by different means.
  • If your librarian has set up your subscription with an OpenURL resolver, OpenURL links appear automatically on the abstract pages.
  • You can define your own OpenURL resolver with your EDPS Account. In this case your choice will be given priority over that of your library.
  • You can use an add-on for your browser (Firefox or I.E.) to display OpenURL links on a page (see http://www.openly.com/openurlref/). You should disable this module if you wish to use the OpenURL server that you or your library have defined.
