Obtain an expression of momentum distribution of -particles in the momentum range
to
, considering the Coulomb correction term. Also, derive the energy distribution function to get the shape of the
-decay spectrum.
For β-decay, consider an electron (or β-particle) emitted from a nucleus. The number of electrons emitted with momentum in the range (p_\beta) to (p_\beta + dp_\beta) is proportional to the phase space available and the Coulomb correction from the nuclear charge. The momentum distribution can be written as: [ dN(p_\beta) \propto F(Z, E_\beta), p_\beta^2 , dp_\beta , (E_0 - E_\beta)^2 ] _________ ____ _________ ___ ________ ____ _____ ______ __________.
