Abstract
The basic equation to describe transport of cosmic rays in a random magnetic field parallel to a magnetic background field is the two-dimensional Fokker-Planck equation. In this paper an investigation of this equation is presented to improve understanding of particle transport, to depict the process of parallel diffusion and to improve recently derived nonlinear transport theories.

Key words: cosmic rays -- turbulence -- diffusion

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.
