So I am asked to detect the number of neutrino events that occur from them entering 3000 metric tonnes of pure water. I am given that t=10s , E(neutrino)=10MeV and that the electron cross section is 10^-47 m^2 . This was the famous neutrino experiment at Kamiokande for the explosion of SN 1987a. I also know the neutrino flux on earth due to this event ~ 4x10^13 s^-1m^-2.
Any help starting off this problem is appreciated!
The Attempt at a Solution
I know I need to find the rate at which electrons are scattered by neutrino collisions in the water . So the reaction is just ν+e-→v+e-.
I'm guessing that the number of events E detected will be E = collisional frequency * elapsed time
