Alpha decay or α-decay isa type of radioactive decay in which an atomic nucleus emits an alpha particle (helium nucleus) and thereby transforms or 'decays' into a different atomic nucleus, with a mass number that is reduced by four and an atomic number that is reduced by two....
1. What is alpha decay? It is a type of nuclear decay in which the nucleus of the atom ejects a particle made of two protons and two neutrons. It is part of the decomposition of an atom that causes it to become an atom of an element with an atomic number higher than the original ...
The alpha decay half-lives of heavy and superheavy nuclei with Z = 80 - 116 are calculated by a deformed double folding model. To obtain the potential between alpha cluster and daughter nucleus, the R3Y-L1, R3Y-W, R3Y-Z, R3Y-HS, R3Y-NL2 and R3Y-NLSH...

(β decay is thought to be the decay of a neutron in the nucleus to a proton and a β, with subsequent emission of the β). When a nuclide emits an α, the atomic mass decreases by 4 and the atomic number decreases by 2.γ emission does not result in a change of either atomic ...
quartet wave function approach (QWFA). It was found that the calculatedαdecay half-life agrees well with the observed data [3,4]. A similar behavior is expected for other nuclei consisting of a double magic core nucleus and an additionalαcluster. Calculations were performed for104Te (100Sn...
Fertilization is internal in rays. Most bear live young, but the skates lay flattened, rectangular eggs, enclosed in leathery shells, with tendrils at the corners for anchorage. Empty egg cases of this type are found on beaches and are known as mermaids' purses. Most ray families have a ...

To understand how the mass number and atomic number change during alpha decay, let's break down the process step by step.Step 1: Understanding Alpha Decay Alpha decay is a type of radioactive decay in which an unstable nucleus
