DefinitionDefinitionThe decay constant (symbol: λ and units: s−1 or a−1) of a radioactive nuclide is its probability of decay per unit time. The number of parent nuclides P therefore decreases with tidoi:10.1007/978-3-642-11274-4_398Francis Albarede...
In addition to the decay constant, radioactive decay is sometimes characterized by the mean lifetime. Each atom "lives" for a finite amount of time before it decays, and the mean lifetime is the arithmetic mean of all the atoms' lifetimes. It is represented by the symbol τ, and is rel...
153. A 250-foot communications tower becomes a symbol of environmental decay as well asa cancer-causing blight on society. 154. But he insisted that organized religion needed to meet the challenge of social unrest and moral decay. 155. The place was littered with barbed wire and rotting lumber...
The girl is the central type and symbol. View in context The conditions fostering the growth of that supreme, alive excellence, as well in work as in play, ought to be preserved with a most careful regard lest the industry or the game should perish of an insidious and inward decay. ...
The equation giving the number (N2) of daughter nuclei existing at time t in terms of the number N1(0) of parent nuclei present when time equals zero isin which e represents the logarithmic constant 2.71828. The general equation for a chain of n generations with only the parent initially ...
where C is the normalization constant. As expected, the probability has a maximum at the point r=rmin and a minimum at r=r0. Substituting (5.4) into (5.9) and introducing a dimensionless parameter, (5.10)a=2γV0K, we find the probability distribution inside the potential well in the ...

Tokyo 169-8555, Japan E-mail: yakkuru 111@ruri.waseda.jp, a.oikawa@aoni.waseda.jp, h.otsuka@aoni.waseda.jp Abstract: We propose the mechanism to disentangle the decay constant of closed string axion from the string scale in the framework of type II string theory on Calabi-Yau mani- fol...
Unstable (i.e., radioactive) species are represented by the chemical symbol of the element with the mass number of the species shown as a subscript to the left and the atomic number shown as a superscript to the left. For example, the widely used radioactive tracer for carbon, carbon-14...
and the result new nuclide is called the daughter nucleus. Every nuclide can be represented as {eq}_{Z}^{A}\textrm{X} {/eq} where the symbol of any nuclide replaces X, A is the atomic mass, and Z is the number of protons. Keep in mind that A=Z+N, where N is the number of...
