penetrating forms of nuclear radiation. ♦ The process by which a radioactive element emits an alpha particle is calledalpha decay. Alpha decay results in the atomic number of the atom being decreased by two and the mass number being decreased by four. See more atradiation,radioactive decay....
The Coulomb potential barrier U is inversely proportional to the distance from the center of the nucleus according to U=(Ze)(ze)/r or Zze2/r, where Z is the atomic number or charge on the nucleus and z is the proton number of the alpha particle (z = 2). Excess energy of the ...

The reason for this prohibition is not found in spin changes in the alpha-emission but in the assembly of the components of the alpha-particle, and this theory is discussed further in terms of observations made on nuclides having two or more alpha-groups. Using most of the even-even nuclei...
Alpha Particle:An alpha particle is an isotope of helium, and is represented by the symbol {eq}\displaystyle ^4_2 He {/eq}. This means that in the atomic model, the composition of the alpha particle is that it is made basically out of two protons and two neutrons....
Alpha nucleus potential has been constructed with the DDM3Y1 interaction, which has an exponential density dependence, in the double folding model using the nucleon densities in the daughter nucleus and the \alpha \alpha particle. Half lives of \alpha \alpha decay have been calculated for ...
