Abstract
The theory is presented for the Raman scattering on bound electrons of neutral donors in the semiconductors with a direct band gap at the incident photon frequency in the resonance with the exciton. The cross-section of the polariton scattering with the transition of the donor electron from the ground state to the first excited state is calculated.

Résumé
Dans ce travail nous présentons la théorie de la diffusion de Raman sur les électrons liés aux donneurs neutres dans les semiconducteurs avec une bande interdite directe, quand la fréquence du photon incident est en résonance avec l'exciton. La section efficace de diffusion du polariton avec transition de l'électron de l'état fondamental au premier état excité a été calculée.

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.
