Nuclear decay equations Brief explanation of the three forms of radioactive emission: alpha, beta and gamma. How to calculate the products of alpha and beta decay? Note: this video is aimed at GCSE Physics students, so does not discuss beta-positive decay or neutrinos/antineutrinos. Try out...
Radioactive decay, also known as nuclear decay or radioactivity, is a random process by which an unstable atomic nucleus loses its energy by emission of radiation or particle. A material containing unstable nuclei is considered radioactive.
The treatment will allow us to determine the concentration of all the nuclear species involved in the series decay. In the second part of the chapter,we consider the processes ofalpha,beta, andgammadecays individually. In each case, our primary purpose is to estimate thedecay constant, the ...
Figure 1. Emission of an alpha particle from the nucleus. Beta Emission Beta (β) decayis a more complicated process. Unlike the α-emission, which simply expels a particle, the β-emission involves the transformation of a neutron in the nucleus to a proton and an electron. The electron i...

Gamma-decay properties of proton resonances in several nuclei along the N=Z line, such as 31S with Gammasphere at ATLAS or 58Zn with GRETINA at NSCL, were determined to further constrain the rp-process path. It is the unique capabilities of the these large γ-ray arrays which allow for ...
Above an excitation energy of \(E^*=1022\) keV, competing to \(2\gamma\) de-excitation is the decay by positron-electron pair creation. A unique ion is \(^{194}\)Pb\(^{82+}\) where the sum of the K-shell electron binding energy (\(BE\sim 101\) keV) and the excitation ...
There are three different types of radiation; alpha, beta, and gamma. Nuclear Fission is when a heavy, unstable nucleus into two lighter nuclei. Nuclear Fusion is the process when two lighter nuclei combine to release a vast amount of energy. Stable Nuclei are nuclei that are stable because ...
