I'm currently working on solar neutrino and in order to make a numerical simulation, I need the potential felt by electron-neutrino : \begin{equation} V_e(r) = \sqrt{2} G_F N_e(r) \end{equation} where $N_e(r)$ is the electron density perceived by the neutrino and $G_F$ the Fermi coupling constant associated to the weak interaction. Do you know any website able to provide me with data or formulas? (I just know that $N_e$ is roughly exponential).

Thank you!

  • $\begingroup$ You should edit the information about symbols into the body of the question. It's not a good idea to expect people to look for additional info like this in comments. $\endgroup$ – StephenG Apr 21 '18 at 16:30

Recently I am also looking for the electron density of sun, and luckily I find it, you can get everything you want in this website, http://www.sns.ias.edu/~jnb/SNdata/solarmodels.html. But it just provide the mass density and the fraction of main elements, so you just need to consider the Molar mass of them.
