src.Atomic.Opacity.H2p_CrossSection(T, wl, n_e, n_H)[source]

return H2+ CrossSection per 1 HI atom n unit of e-26 cm^2 in LTE

Parameters

  • T (Temperature [\(K\)]) –

  • wl (wavelength [\(\AA\)]) –

  • n_e (electron number density [\(cm^{-3}\)]) –

  • n_H (hydrogen number density [\(cm^{-3}\)]) –

Notes

H2+ opacity in LTE is

kH2p = n_HI * H2p_CrossSection(T,wl,n_e,n_H) * 1.e-26 (/cm)

use avH2p(T,wl)
