Mean free path of UV photon The absorber is another H2 molecules and dust particles (you can assume that the dust density scales with the gas density and is proportional to the metallicity of the gas). |

Mean free path of UV photon Thanks, but the problem here is where to find the absorption cross section of UV photons, better as a function of wavelength. |

Mean free path of UV photon By density I mean atoms per volume and the photons are only absorbed by the medium |

Mean free path of UV photon It's an expression of the cross section that I would like to find out. The problem is computing the mean free path of UV photons in a molecular cloud where dust and H2 are responsible for absorption. You can also assume that the dust density is proportional to the metallicity of the gas. |
