In nuclear physics, beta decay (β-decay) is a type of radioactive decay in which a beta particle (fast energetic electron or positron) is emitted from an atomic nucleus... For example, beta decay of a neutron transforms it into a proton by the emission of an electron...
What is emitted in alpha decay? Radioactive Decay: During radioactive decay, one atom releases particles as well as energy from its nucleus. Radioactive decay can take one of three forms depending on the particles and amount of energy released: alpha decay, beta decay or gamma rays. Answer ...
Recent tritium beta decay experiments yield unphysical negative best-fit values for the square of the neutrino mass. An unidentified bump-like excess of counts few eV below the endpoint in the electron energy spectrum has been tentatively recognized as the source of this anomaly. It is shown tha...
The aim is to check how the self-consistency is preserved in the calculations for long isotopic chains. The beta-decay half-lives and delayed multi-neutron emission branching are calculated for the reference Ni isotopic chain. The relative contributions of the GT and first-forbidden transitions ...

We investigate the rare parts of the neutron beta decay processes, n --> p + e- + bar{nu}e and n --> H + bar{nu}e (H is the hydrogen atom) (beside the dominant exponentially decaying part), whose time dependences are inversely proportional to the 6th and 3rd (for massive neutrin...

Since Fermi-type beta decays are forbidden in N=Z even-even nuclei, it is pointed out that the main decay mode of the nuclei such as Snmay be ``superallowed'' GT beta decay, which is a beta decay to the GT giant resonance state. The amplitude of isospin T=1 admixed to the T=...
The measurement of positron--nucleus collisions was used to estimate the possibility of suppressing background events that simulate $\beta\beta$ decay in the emulsion region adjacent to molybdenum conglomerates. The range of the escape of two relativistic particles from the interaction was found to ...
