Im being asked what is the minimum energy requiered for the proccess
e + p -> nutrino + nutron
assumptions are: 1. Kinetic energy of proton is much lower from his rest
mass, not true for the electron.
2. border line case is when nutrino energy is close to zero.
energy and momentum conservation, pc = sqrt(E^2 - m0^2*c^4) ?
The Attempt at a Solution
i should use energy and momentum conservation but i have no idea how to
do that since i dont know what are the kinetic energies of the
proton and electron.
thank you for any help avaiable
