DOI: 10.1093/mnras/sty1189
Abstract: Calculations of hydrogen departure coefficients using a model with the angular momentum quantum levels resolved that includes the effects of external radiation fields are presented. The stimulating processes are important at radio frequencies and can… read more here.
