An Idea About Beta Decay

How can we possibly explain the continuous spectrum of electron energies in beta decay without having to invent another particle to properly arrive at conserved energy and momentum? There are two factors that give me hope that a solution is possible. One is the extreme difference in mass between the unstable nucleus and the escaping electron. For example, what was known as Radium E is, in fact, Bismuth - 210. This nucleus has a mass approximately 382,000 times bigger than the electron. Secondly, all atoms in solids undergo thermal oscillations. Thus, a decaying nucleus will have a unique velocity at the instant of ejection of the electron. The velocity distribution of the nuclei may be intimately related to the spectrum of the ejected electrons. This seems worth looking into.

If this is correct, then we would expect to see some much smaller variation in the energies of alpha particles ejected in alpha decay.

Neutrinos? You're Kidding Me

I'm certainly not the first person that says that neutrinos do not exist. I'm pretty certain that the invention of the neutrino was one of the big boondoggles of modern physics. I would say that Wolfgang Pauli and the others rushed the solution of the problem of the continuous spectrum of the kinetic energy (or speed if you prefer) of the electrons that emerge from the nucleus in beta decay. At the moment I cannot prove it, but I feel fairly certain that the correct explanation lies somewhere in a proper accounting of all the energy and momentum involved in the decay process without neutrinos. Also, I have not yet found a fatal flaw in the 1956 experiments of Frederick Reines and Clyde Cowan, the first time physicists claimed to have observed neutrinos (albeit fairly indirectly). I am open to sensible suggestions and/or experimental results on either side of the hypothesis.
