Positron emission, beta plus decay, or β + decay is a subtype of radioactive decay called beta decay, in which a proton inside a radionuclide nucleus is converted into a neutron while releasing a positron and an electron neutrino (ν e). [1] Positron emission is mediated by the weak force.
The abundances of the naturally occurring isotopes of neon. Neon (10 Ne) possesses three stable isotopes: 20 Ne, 21 Ne, and 22 Ne. In addition, 17 radioactive isotopes have been discovered, ranging from 15 Ne to 34 Ne, all short-lived. The longest-lived is 24 Ne with a half-life of 3.38(2) min. All others are under a minute, most under a second.
Disk containing 1 μCi of sodium-22. Sodium-22 is a radioactive isotope of sodium, undergoing positron emission to 22 Ne with a half-life of 2.6019(6) years. 22 Na is being investigated as an efficient generator of "cold positrons" to produce muons for catalyzing fusion of deuterium.

In this snippet from volume two of the Yahoo Finance Chartbook, economists and equity strategists break down why recession hasn't hit the US economy amid the Fed's interest rate hiking cycle.
A chart or table of nuclides maps the nuclear, or radioactive, behavior of nuclides, as it distinguishes the isotopes of an element.It contrasts with a periodic table, which only maps their chemical behavior, since isotopes (nuclides that are variants of the same element) do not differ chemically to any significant degree, with the exception of hydrogen.
An overarching feeling of optimism about both the economy and markets emerges from the third volume of the Yahoo Finance Chartbook, a trend similar to that seen in volume two in late January.
