The Theory of Alpha Decay
One of the relatively simple physical processes that can be described successfully in the framework of introductory quantum theory is alpha decay. In this process, two protons and two neutrons out of a relatively large nucleus dissociate from the rest of the nucleus, form a separate subsystem and subsequently depart. In its full complexity, this process is not be describable, however a reasonab...
متن کاملQuantum Mechanics of Alpha Decay
Quantum mechanical basis for the Geiger-Nuttal Law. Determination of the half-lives of several species in the Uranium, Thorium and Actinium series through the use of a scintillator, solid-state detector and coincidence circuitry. The half-lives of Po, Rn and Po are determined at 181 ± 5 s, 4.49 ± .01 days and 163 ± 1 μs, respectively. Verification of the theoretical relationship between half-li...
متن کاملNeutrinoless Double Beta Decay and Its “inverse”
Recent considerations by these authors pointed out the attractive features which a search for the exchange of heavy Majorana neutrinos could have for solving the mass and the lepton number puzzles for all neutrinos, in TeV-level electron-electron scattering. In the present note, we show that, contrary to subsequently published arguments, non-observation of neutrinoless double beta decay has, to...
متن کاملInverse beta-decay in magnetic fields
We calculate the cross section of the inverse beta decay process, νe + n → p + e, in a magnetic field which is much smaller than m2p/e. Using exact solutions of the Dirac equation in a constant magnetic field, we find that the cross section depends on the direction of the incident neutrino even when the initial neutron is assumed to be at rest. We discuss the implication of this result for puls...
متن کاملInverse Neutrinoless Double Beta Decay Revisited
We critically reexamine the prospects for the observation of the ∆L = 2 lepton-numberviolating process ee → WW using the ee option of a high-energy e+e− collider (NLC). We find that, except in the most contrived scenarios, constraints from neutrinoless double beta decay render the process unobservable at an NLC of √ s < 2 TeV. Other ∆L = 2 processes such as γγ → l+l+W−W−, eγ → νellW, ee → νeνel...
