3. (a) (1 point) The nuclear beta decay process was originally thought to be n pt +e. What were the problems with this two body decay. (b) (5 points) For the three body decay process n pt +e +Ve; use Fermi's golden rule for transition rate between a bound state and a continuum of states to show that the probability that an electron is emitted with momentum between pe and pe + dp. is given by, P(p.) = CF(Z, E.) (E, - E.)*dp. where C is a collection of constants.
