Far UV radiation transfer and H2CO lifetime in dense interstellar clouds

  • S. Aiello

The UV radiation transfer within spherical interstellar dust clouds is analyzed using the method of successive scatterings. The results are used to determine the lifetime of interstellar H2CO against photo-destruction. The effectiveness of this process is compared with those of chemical mechanisms.
