Secondly, he found the charge-to-mass ratio of alpha particles to be half that of the hydrogen ion. Rutherford proposed three explanations: 1) an alpha particle is a hydrogen molecule (H 2) with a charge of 1 e; 2) an alpha particle is an atom of helium with a charge of 2 e; 3) an alpha particle is half a helium atom with a charge of 1 e.
Alpha strike may refer to: Alpha strike (engineering), when an alpha particle enters and causes damage to the data contained in a computer processor; Alpha strike (gaming), a massive, all-out attack, as in a tabletop wargame; Alpha strike (United States Navy), a large air attack by an aircraft carrier air wing
Discovery of alpha particle effects on computer chips [ edit ] As an engineer, May was most noted for having identified the cause of the " alpha particle problem ", which was affecting the reliability of integrated circuits as device features reached a critical size where a single alpha particle could change the state of a stored value and ...
Alpha particles consist of two protons and two neutrons bound together into a particle identical to a helium nucleus. Alpha particle emissions are generally produced in the process of alpha decay . Alpha particles are a strongly ionizing form of radiation, but when emitted by radioactive decay they have low penetration power and can be absorbed ...
Alpha spectrometry (also known as alpha(-particle) spectroscopy) is the quantitative study of the energy of alpha particles emitted by a radioactive nuclide that is an alpha emitter. As emitted alpha particles are mono-energetic (i.e. not emitted with a spectrum of energies, such as beta decay ) with energies often distinct to the decay they ...

Computing the total disintegration energy given by the equation = (), where m i is the initial mass of the nucleus, m f is the mass of the nucleus after particle emission, and m p is the mass of the emitted (alpha-)particle, one finds that in certain cases it is positive and so alpha particle emission is possible, whereas other decay modes ...
The alpha particle is an especially strongly bound nucleus, helping it win the competition more often. [57]: 872 However some nuclei break up or fission into larger particles and artificial nuclei decay with the emission of single protons, double protons, and other combinations. [55] Beta decay transforms a neutron into proton or vice versa.
