Neutrino Decoupling Function

  1. Apr 21, 2015 #1
    Neutrinos decouple at around 10^10 K (or 1 MeV). This is normally shown as the interaction rate (between neutrinos and electrons) over the hubble constant: Gamma/H = (T/10^10 K)^3

    My problem:
    I have a function which is dependent on the neutrino-electron interaction. But it does not take the neutrino decoupling into account. I am unsure about how I should (very simply) incorporate this into my function.
    1) Should I add a stepfunction from 1 to 0 at 1 MeV?
    2) Should I use a smoother function? Like e^-(10^10 K / T)^3 ?
    3) Something else?

    Cheers! :)
