Indium (49 In) consists of two primordial nuclides, with the most common (~ 95.7%) nuclide (115 In) being measurably though weakly radioactive. Its spin-forbidden decay has a half-life of 4.41×10 14 years, much longer than the currently accepted age of the Universe. The stable isotope 113 In is only 4.3% of
Conversely, of the 251 known stable nuclides, only five have both an odd number of protons and odd number of neutrons: hydrogen-2 , lithium-6, boron-10, nitrogen-14, and tantalum-180m. Also, only four naturally occurring, radioactive odd–odd nuclides have a half-life >10 9 years: potassium-40 , vanadium-50 , lanthanum-138 , and lutetium-176 .
The stable indium isotope, indium-113, is one of the p-nuclei, the origin of which is not fully understood; although indium-113 is known to be made directly in the s- and r-processes (rapid neutron capture), and also as the daughter of very long-lived cadmium-113, which has a half-life of about eight quadrillion years, this cannot account for ...

The majority of ethnic-language broadcasts in North America are carried on K u band free-to-air. The largest concentration of free-to-air programming is on Galaxy 19 at 97° W. Pittsburgh International Telecommunications and GlobeCast World TV offers a mix of free and pay-TV ethnic channels in the internationally standard DVB-S and S2 formats ...
The heaviest stable element, lead (Pb), has many more neutrons than protons. The stable nuclide 206 Pb has Z = 82 and N = 124, for example. For this reason, the valley of stability does not follow the line Z = N for A larger than 40 ( Z = 20 is the element calcium ). [ 3 ]
[6] [27] Protons share the first six of these magic numbers, [28] and 126 has been predicted as a magic proton number since the 1940s. [29] Nuclides with a magic number of each—such as 16 O ( Z = 8, N = 8), 132 Sn ( Z = 50, N = 82), and 208 Pb ( Z = 82, N = 126)—are referred to as "doubly magic" and are more stable than nearby nuclides as a ...
The aim of this experiment had been to synthesise the isotopes 281 113 and 282 113 that would fill in the gap between isotopes produced via hot fusion (283 113 and 284 113) and cold fusion (278 113). After five alpha decays, these nuclides would reach known isotopes of lawrencium , assuming that the decay chains were not terminated prematurely ...
