| Nov 12, 2020 at 4:37 | comment | added | G. Smith | If I didn’t de-dimensionalize, I had to use the option Method->”DoubleExponential” with NIntegrate[] in Mathematica. Otherwise, I got $0$. | |
| Nov 12, 2020 at 4:24 | comment | added | G. Smith | I had no trouble evaluating the integral numerically after de- dimensionalizing it. | |

| Nov 11, 2020 at 22:12 | comment | added | G. Smith | You are probably having trouble because you didn’t de-dimensionalize the integral. | |
| Nov 11, 2020 at 22:10 | comment | added | Vincent ISOZ | @G.Smith I wrote "seems to fail" and not just "fail". The point is something cause a problem (whatever it is: very likely because of my ignorance). | |
| Nov 11, 2020 at 21:54 | comment | added | G. Smith | How could the convergence fail when the integrand becomes exponentially small as $E\to\infty$? | |
| Nov 11, 2020 at 21:48 | comment | added | Vincent ISOZ | @G.SmithThe lower limit is not zero because we are interested only on photons that have an energy higher that the first level of ionization of the Hydrogen atom (13.6 eV) | |
| Nov 11, 2020 at 21:47 | comment | added | Vincent ISOZ | @G.Smith "i failed" mean that with all my softwares the convergence seems to fail. | |
| Nov 11, 2020 at 21:47 | comment | added | Vincent ISOZ | @G.Smith The units are [J] ( the equivalent of 13.6 [eV]) | |

| Nov 11, 2020 at 20:54 | comment | added | G. Smith | Why is the lower limit not zero? Photons of arbitrarily low energy contribute to the number density. | |
| Nov 11, 2020 at 20:48 | comment | added | G. Smith | What does “I failed” mean? What prevented you from obtaining a numerical integration? | |
| Nov 11, 2020 at 20:47 | comment | added | G. Smith | What are the units of $2.1789\cdot 10^{-18}$? | |
